Achieving controlled and site-specific delivery of hydrophobic drugs in the colon environment is a major challenge. The primary goal of this research was to synthesize inulin-stearic acid (INU-SA) conjugate and to evaluate its potential in the site-specific delivery of genistein (GEN) for the treatment of colon cancer. INU is a hydrophilic polysaccharide biol. macromol. was modified with hydrophobic SA to form amphiphilic conjugate (INU-SA) which can self-assemble into spherical nanoparticles with interesting drug release properties. The hydrophobic GEN was encapsulated into the INU-SA conjugate to prepare GEN loaded nanoparticles (GNP). The prepared GNP possessed nano size (115 nm), good colloidal dispersibility (0.066 PDI), and high drug encapsulation efficiency (92.2%). The release behavior of GNP indicated the site-specific release of GEN, only 3.4% at gastric pH while 94% at intestinal pH. The prepared GNP showed potential cytotoxicity against HCT 116 human colorectal cancer cells, as demonstrated by antiproliferation and apoptosis assays. The observed half maximum inhibitory concentration (IC50) value of GNP (5.5μg/mL) was significantly lower than pure GEN (28.2μg/mL) due to higher cellular internalization of GNP than free GEN. Therefore, this research suggests a way to improve the therapeutic effectiveness of natural biomols. using modified and biocompatible polysaccharide INU. This study involved multiple reactions and reactants, such as 3-(Benzo[d]thiazol-2-yl)-7-(diethylamino)-2H-chromen-2-one (cas: 38215-36-0Quality Control of 3-(Benzo[d]thiazol-2-yl)-7-(diethylamino)-2H-chromen-2-one).

3-(Benzo[d]thiazol-2-yl)-7-(diethylamino)-2H-chromen-2-one (cas: 38215-36-0) belongs to thiazole derivatives. The higher aromaticity of thiazole is due to delocalization of a lone pair of sulfur electrons across the ring, which is evidenced by chemical shifts of ring hydrogen at δ 7.27 and 8.77 ppm (C2 and C4), indicating diamagnetic ring current. The nitrogen in thiazole is sp2 hybridized and the lone pair of electrons localized on the nitrogen is less reactive due to increased aromatic character and decreased basicity. It is protonated and alkylated/acylated at nitrogen forming hydrochloride and quaternary thiazolium salt.Quality Control of 3-(Benzo[d]thiazol-2-yl)-7-(diethylamino)-2H-chromen-2-one

Pifithrin-α enhancing anticancer effect of topotecan on p53-expressing cancer cells was written by Guo, Jianli;Tang, Qin;Wang, Qingling;Sun, Wenhui;Pu, Zhongji;Wang, Jingyun;Bao, Yongming. And the article was included in European Journal of Pharmaceutical Sciences in 2019.COA of Formula: C16H19BrN2OS The following contents are mentioned in the article:

P53 is generally known as an effective anti-cancer mol., but it is lost or mutated in more than 50% of human tumors. It is still a controversial issue whether the activity of p53 really benefits for treating cancers, we wondered what would happen if the endogenous p53 was inhibited before treated with topotecan (TPT) on p53 pos. tumor cells. In this study, pifithrin-α (PFTα), a p53 inhibitor, was used 2 h before treated with TPT on three kinds of cancer cell lines including MCF7, BGC823 and HepG2 cells. The IC50s of TPT for MCF7, BGC823 and HepG2 cells after 10μΜ PFTα pretreated, was 4.8 to 14.4 folds lower than the effect of TPT alone. It was demonstrated that PFTα decreases the p-p53 levels and p-p53 activity, not affects p53 expression in p53 pos. tumor cells. PFTα enhanced anticancer effect of TPT on cells was found mainly by two ways. Firstly, it increased the TPT accumulation in cells and nucleus and promoted the inhibition of TPT on activity of Topo I, and induced more DNA damage. Secondly, PFTα decreased formation of p53/mdm2 complex responsible for p53 degradation by inhibiting the protein expression of mdm2, so p53 degradation was decreased in cytoplasm and p53 accumulation was increased in nucleus, which induced more cells undergo apoptosis. So, the crosstalk between p53 and TPT played a pivotal role for enhancing anticancer effects of PFTα and TPT on p53 pos. cancer cells. This study involved multiple reactions and reactants, such as 2-(2-Imino-4,5,6,7-tetrahydrobenzothiazol-3-yl)-1-p-tolylethanone Hydrobromide (cas: 63208-82-2COA of Formula: C16H19BrN2OS).

Efficacy of mimetic viral dynein binding peptide binding nanoparticles in blood-brain barrier model was written by Liu, Nan;Li, Mingyuan;Xie, Fang;Lv, Jiaqi;Gao, Xiaoyi;Zhang, Hui;Gao, Jing;Zheng, Aiping. And the article was included in Journal of Drug Delivery Science and Technology in 2022.SDS of cas: 38215-36-0 The following contents are mentioned in the article:

The blood-brain barrier (BBB) is a tight barrier that protects stability of the central nervous system (CNS), however, the mechanism impedes the delivery of drugs to the CNS. The interactions between viral proteins and cytoplasmic dynein during infection have been found. In this study, the “linker (dynein binding peptide, DBP)” between virus and dynein was reformed and connected with nanoparticles to try to penetrate the blood-brain barrier. Co-IP and intracellular studies with the designed peptides revealed their interactions with the dynein and their rapid uptake by bEnd.3 cells. And the DBP binding with the cell-penetrating peptide (CPP) exhibited the best intracellular uptake. The peptides were conjucted with DSPE-PEG2000 and prepared to nanoparticles loaded with coumarin-6 (Cou-6). All of the prepared nanoparticles were around 25 nm in size, even though they had different modifications. The 10% DBP-CPP modified coumarin-6-loaded nanocarrier exhibited rapid intracellular distribution and cellular uptake. Transwell studies clearly showed the intercellular transport of the nanoparticles. The study is the first to combine DBP-CPP with a nanodelivery drug carrier and to apply it in a BBB model. The results of our in vitro studies results revealed that DBP can mediate permeation of nanoparticles across the BBB, which may serve as a clin. viable strategy for drug delivery in the brain. This study involved multiple reactions and reactants, such as 3-(Benzo[d]thiazol-2-yl)-7-(diethylamino)-2H-chromen-2-one (cas: 38215-36-0SDS of cas: 38215-36-0).

3-(Benzo[d]thiazol-2-yl)-7-(diethylamino)-2H-chromen-2-one (cas: 38215-36-0) belongs to thiazole derivatives. Thiazole rings are planar and aromatic. Thiazoles are characterized by larger pi-electron delocalization than the corresponding oxazoles and have therefore greater aromaticity. The pyridine-type nitrogen in the thiazole ring deactivates the ring for electrophilic substitution reactions, which is further reduced in acid due to protonation of the thiazole ring.SDS of cas: 38215-36-0

Zearalenone induces endothelial cell apoptosis through activation of a cytosolic Ca²⁺/ERK1/2/p53/caspase 3 signaling pathway was written by Lee, Hyeon-Ju;Oh, Se-Young;Jo, Inho. And the article was included in Toxins in 2021.Category: thiazole The following contents are mentioned in the article:

Zearalenone (ZEN) is a mycotoxin that has been reported to damage various types of cells/tissues, yet its effects on endothelial cells (ECs) have never been investigated. Therefore, this study investigates the potential effects of ZEN using bovine aortic ECs (BAECs). In this study, we found that ZEN induced apoptosis of BAECs through increased cleavage of caspase 3 and poly ADP-ribose polymerase (PARP). ZEN also increased phosphorylation of ERK1/2 and p53, and treatment with the ERK1/2 or p53 inhibitor reversed ZEN-induced EC apoptosis. Transfection of BAECs with small interfering RNA against ERK1/2 or p53 revealed ERK1/2 as an upstream target of p53 in ZEN-stimulated apoptosis. ZEN increased the production of reactive oxygen species (ROS), yet treatment with the antioxidant did not prevent EC apoptosis. Similarly, blocking of estrogen receptors by specific inhibitors also did not prevent ZEN-induced apoptosis. Finally, chelation of cytosolic calcium (Ca²⁺) using BAPTA-AM or inhibition of endoplasmic reticulum (ER) Ca²⁺ channel using 2-APB reversed ZEN-induced EC apoptosis, but not by inhibiting ER stress using 4-PBA. Together, our findings demonstrate that ZEN induces EC apoptosis through an ERK1/2/p53/caspase 3 signaling pathway activated by Ca²⁺ release from the ER, and this pathway is independent of ROS production and estrogen receptor activation. This study involved multiple reactions and reactants, such as 2-(2-Imino-4,5,6,7-tetrahydrobenzothiazol-3-yl)-1-p-tolylethanone Hydrobromide (cas: 63208-82-2Category: thiazole).

2-(2-Imino-4,5,6,7-tetrahydrobenzothiazol-3-yl)-1-p-tolylethanone Hydrobromide (cas: 63208-82-2) belongs to thiazole derivatives. Thiazoles are a class of five-membered rings containing nitrogen and sulfur with excellent antitumor, antiviral and antibiotic activities. Electrophilic attack at nitrogen depends on the presence of electron density at nitrogen as well as the position and nature of substituent linked to the thiazole ring.Category: thiazole

Pifithrin-α Inhibits Neural Differentiation of Newborn Cells in the Subgranular Zone of the Dentate Gyrus at Initial Stages of Audiogenic Kindling in Krushinsky-Molodkina Rat Strain was written by Kulikov, A. A.;Nasluzova, E. V.;Dorofeeva, N. A.;Glazova, M. V.;Lavrova, E. A.;Chernigovskaya, E. V.. And the article was included in Journal of Evolutionary Biochemistry and Physiology in 2021.Electric Literature of C16H19BrN2OS The following contents are mentioned in the article:

We hypothesized that a proapoptotic protein p53 can be one of the possible therapeutic targets in treating epilepsy and its neurodegenerative consequences. In the present work, we used the Krushinsky-Molodkina (KM) inbred rats, which are genetically prone to audiogenic seizures (AGS). Audiogenic kindling, a commonly accepted model of epileptogenesis, induces epileptiform activity in the limbic system and cerebral cortex. In KM rats, it has been shown that 4 AGS lead to an increase in proliferation, aberrant migration of newborn cells to the hilus, and accelerated neural differentiation of these cells. We revealed abnormalities neither in apoptosis nor in autophagy levels at the initial stages of temporal lobe (limbic) epilepsy. Treatment with pifithrin-α, a chem. p53 inhibitor, did not change apoptosis and autophagy levels but caused an increase in proliferation and migration of newborn cells to the granule cell layer of the dentate gyrus and to the hilus. However, a week after the last seizure, p53 inactivation entailed a decrease in the number of differentiating cells, as compared to the vehicle control group, despite a significant increase in the number of newborn cells. These data indicate a decrease in the neural differentiation rate of newborn cells, thus allowing pifitrin-α to be considered as a potential therapeutic agent to alleviate neurodegenerative disorders in epilepsy. This study involved multiple reactions and reactants, such as 2-(2-Imino-4,5,6,7-tetrahydrobenzothiazol-3-yl)-1-p-tolylethanone Hydrobromide (cas: 63208-82-2Electric Literature of C16H19BrN2OS).

And the article was included in Pharmaceutical Development and Technology in 2022.Recommanded Product: 3-(Benzo[d]thiazol-2-yl)-7-(diethylamino)-2H-chromen-2-one The following contents are mentioned in the article:

In this study, amphiphilic block copolymer mPEG-cholic acid was synthesized in conjunction with TPGS as stabilizer to prepare multifunctional micelles. The formed polymeric micelles (PCTm) were used for the delivery of paclitaxel (PTX) and bufalin (BF). PEG group could enhance solubility and extend circulation time, while cholic acid groups achieved the liver targeted function. Combinations of these approaches could realize a synergistic therapeutic effect in the treatment of advanced hepatocellular carcinoma. CLSM in vitro results demonstrated that drug capsulation into PCTm could enhance cellular uptake. FCM results confirmed the uptake amount of C₆/PCTm was 7.5-fold higher than that of free C₆ after incubation for 2 h. Competitive inhibition test proved the Na⁺-taurocholate co-transporting polypeptide (NTCP) involved in the uptake mechanism of PCTm. Meanwhile, in vivo imaging assays demonstrated that the fluorescence intensity of Cy5.5/PCTm was higher than that of free Cy5.5 on liver and tumor with extended circulation time to 48 h. In addition, in vivo studies confirmed that the combined therapy exhibited the strongest tumor inhibition rate of 82.29% with lower systemic toxicity. Hence, these results indicated that PCTm could provide a promising strategy for targeting hepatocellular carcinoma and achieve the goal of synergism and attenuation.

And the article was included in Journal of Colloid and Interface Science in 2021.Recommanded Product: 38215-36-0 The following contents are mentioned in the article:

The micro-volume anal. and specific detection are both essential requirements in the field of chem. sensing and biol. testing. Membrane prefiltration can be used to improve the selectivity and accuracy of detection. But for traditional porous membrane filtration, it is difficult to achieve the transmembrane transport of micro-volume liquid due to the influence of lateral diffusion on membrane surface. Herein, we studied the focused transmembrane transport of micro-volume liquid in the porous polyethersulfone membrane with asym. (Janus) surface wettability. The hydrophilic layer (polydopamine) and hydrophobic layer (fluoropolymer) were deposited with controllable thickness by dip-coating and roller-assisted liquid printing. The micro-volume liquid focusing effect was verified by experiments such as visual wetting circle and fluorescent tracer. The liquid focusing effect of as-prepared Janus membrane was integrated with glucose test strip in the application of micro-volume liquid biosensing. Compared with conventional porous membrane, detected signal amplitude and response time were improved 7.5x and 2.7x, resp. In summary, this research studied the dynamics of liquid transport through Janus membrane and provides a new strategy for microfluidic detection applications through balancing detection volume, time and selectivity by the advantage of micro-volume liquid focusing effect.

Hepatocellular carcinoma (HCC) is one of the most common cancers. MicroRNA has been studied more and more deeply and may become a new target for the treatment of HCC. Here, we investigated the role of miR-455-3p in HCC progression. Compared with non-tumor tissues and normal human hepatic cells, miR-455-3p expression was significantly downregulated in HCC tissues and cell lines. And overexpression of miR-455-3p inhibited cell proliferation and migration but promoted cell apoptosis in HCC cell lines HepG2 and Huh7. Mechanism studies displayed that miR-455-3p targeted HDAC2 and neg. regulated HDAC2 expression. Moreover, HDAC2 was highly expressed in HCC tissues and cell lines. Overexpression of HDAC2 reversed the inhibitory effects of miR-455-3p on cell proliferation, migration and cell cycle protein (CDK6 and cyclin D1) expression, and neutralized the promotion effects of miR-455-3p on cell apoptosis and the activation of p53 pathway. Furthermore, a p53 inhibitor Pifithrin-α (PFT-α) effectively abolished the effects of miR-455-3p on HCC cell behaviors. Addnl., the role of miR-455-3p in tumorigenesis was evaluated by using a mouse xenograft model, and the data showed that miR-455-3p suppressed tumor growth in vivo. In summary, our results suggested that miR-455-3p targeted HDAC2 to inhibit cell proliferation, migration and promote cell apoptosis via the activation of p53 pathway.

JK184 can specially inhibit Gli in the Hedgehog (Hh) pathway, which showed great promise for cancer therapeutics. For developing aqueous formulation and improving anti-tumor activity of JK184, we prepared JK184 encapsulated MPEG-PCL micelles by the solid dispersion method without using surfactants or toxic organic solvents. The cytotoxicity and cellular uptake of JK184 micelles were both increased compared with the free drug. JK184 micelles induced more apoptosis and blocked proliferation of Panc-1 and BxPC-3 tumor cells. In addition, JK184 micelles exerted a sustained in vitro release behavior and had a stronger inhibitory effect on proliferation, migration and invasion of HUVECs than free JK184. Furthermore, JK184 micelles had stronger tumor growth inhibiting effects in s.c. Panc-1 and BxPC-3 tumor models. Histol. anal. showed that JK184 micelles improved anti-tumor activity by inducing more apoptosis, decreasing microvessel d. and reducing expression of CD31, Ki67, and VEGF in tumor tissues. JK184 micelles showed a stronger inhibition of Gli expression in Hh signaling, which played an important role in pancreatic carcinoma. Furthermore, circulation time of JK184 in blood was prolonged after entrapment in polymeric micelles.
