Glioblastoma (GBM) is a difficult-to-treat cancer, likely attributed to the blood brain barrier and drug resistance. Nose-to-brain drug delivery is a direct and non-invasive pathway for brain targeting with low systemic toxicity. Disulfiram (DSF) has shown its effectiveness against GBM, especially with copper ion (Cu). In this work, we designed a DSF loaded ion-sensitive nanoemulsion in situ gel (DSF-INEG) that was delivered intranasally along with Cu to the rat brains for the GBM treatment. The developed DSF-INEG nanomedicine showed a suitable particle size of 63.4 ± 1.1 nm and zeta potential of -23.5 ± 0.2 mV with a favorable gelling ability and prolonged DSF release. The results in vitro indicate DSF-INEG/Cu effectively inhibited the proliferation of both C6 and U87 cells. Besides, the excellent brain-targeting efficacy via nose-to-brain delivery was proved by the highest fluorescence signal of Cy5.5-INEG in the rat brains. Moreover, GFP imaging showed enhanced tumor growth inhibition of the rats by the DSF-INEG/Cu treatment, and their median survival time was 1.6 and 1.2 folds than those of the rats in the control and DSF/Cu treated groups, resp., with no obvious histopathol. damage to normal tissues. Overall, DSF-INEG/Cu could be a promising intranasal nanomedicine for effective GBM treatment. This study involved multiple reactions and reactants, such as 3-(Benzo[d]thiazol-2-yl)-7-(diethylamino)-2H-chromen-2-one (cas: 38215-36-0Category: thiazole).

3-(Benzo[d]thiazol-2-yl)-7-(diethylamino)-2H-chromen-2-one (cas: 38215-36-0) belongs to thiazole derivatives. Thiazoles frequently appear in peptide studies. Thiazoles can also be used as protected formyl groups, which can be released in later stages of complex natural product synthesis. 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.Category: thiazole

Improved bioavailability and anticancer efficacy of Hesperetin on breast cancer via a self-assembled rebaudioside A nanomicelles system was written by Wang, Jun;Li, Qiqi;Chen, Zekun;Qi, Xueju;Wu, Xianggen;Di, Guohu;Fan, Junting;Guo, Chuanlong. And the article was included in Toxicology and Applied Pharmacology in 2021.Quality Control of 3-(Benzo[d]thiazol-2-yl)-7-(diethylamino)-2H-chromen-2-one The following contents are mentioned in the article:

Hesperetin (HSP) has excellent biol. activities with poor water solubility which limits its clin. development. In this study, we successfully prepared a novel, self-assembled micelle based on Rebaudioside A (RA) for oral delivery of HSP with improved bioavailability and therapeutic effects. We found that RA and HSP could be formylated into nanomicelles with particle sizes of 4.541 nm ± 0.048 nm. HSP was readily encapsulated into RA micelles and this improved its water solubility (to 12.74 mg/mL ± 0.28 mg/mL). The MTT results showed that RA-HSP enhanced the cytotoxicity, the clonal formation inhibitory activity, and cell migration inhibitory activity of HSP in human breast cancer MDA-MB-231 cells. The mechanism results showed that RA-HSP induced cell apoptosis by inducing the production of reactive oxygen species (ROS), destroying the mitochondrial membrane potential (MMP), and inhibiting the PI3K/Akt signaling pathway. Moreover, RA-HSP enhanced the anticancer activity, increased the oral bioavailability and tissue distribution of HSP in vivo. Moreover, the mechanism studies in vivo found that HSP inhibited PI3K/Akt signaling pathway with low side effects. These findings indicate that RA micelle formulations have great potential in oral drug delivery systems for the delivery of hydrophobic drugs. 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. Thiazole rings are planar and aromatic. Thiazoles are characterized by larger pi-electron delocalization than the corresponding oxazoles and have therefore greater aromaticity. Thiazole sulfonation occurs only under forcing conditions: the action of oleum at 250 °C for 3 hours in the presence of mercury(II) sulfate leads to 65% formation of 5-thiazole sulfonic acid.Quality Control of 3-(Benzo[d]thiazol-2-yl)-7-(diethylamino)-2H-chromen-2-one

Botrytis cinerea, responsible for gray mold diseases, is a pathogen with a broad host range, affecting many important agricultural crops, in pre and post harvesting of fruits and vegetables. Com. fungicides used to control this pathogen are often subjected to photolysis, volatilization, degradation, leaching, and runoff during application. In this context, the use of a delivery system, based on poly (lactic-co-glycolic acid) nanoparticles (PLGA NPs) represents an innovative approach to develop new pesticide formulations to successfully fight B. cinerea infections. In order to study NPs uptake, B. cinerea conidia and mycelium were treated with PLGA NPs loaded with the high fluorescent probe coumarin 6 (Cu6-PLGA NPs) and analyzed under ApoTome fluorescence microscopy. The observations revealed that 50 nm Cu6-PLGA NPs penetrated into B. cinerea conidia and hyphae, as early as 10 min after administration. Pterostilbene, a natural compound, and fluopyram, a synthetic antifungal, were entrapped in PLGA NPs, added to B. cinerea conidia and mycelium, and their antifungal activity was tested. The results revealed that the compounds loaded in NPs exhibited a higher activity against B. cinerea. These results lay the foundations for the use of PLGA NPs as a new strategy in plant pest management. This study involved multiple reactions and reactants, such as 3-(Benzo[d]thiazol-2-yl)-7-(diethylamino)-2H-chromen-2-one (cas: 38215-36-0Name: 3-(Benzo[d]thiazol-2-yl)-7-(diethylamino)-2H-chromen-2-one).

Cabazitaxel (CZT) loaded chitosan-alginate based (CSA) nanoparticles were developed with dual targeting functions of both folate receptor and epidermal growth factor receptor (EGFR) using ionic gelation technique. The chitosan-folate conjugate was synthesized, and characterized by using FTIR, NMR and Mass spectroscopy. The physicochem. parameters and morphol. of all CSA nanoparticles were examined The degree of conjugation of folic acid and cetuximab (CTXmab) was determined by UV-Visible spectroscopy and Bradford assay, resp. Moreover, XPS anal. also supported the presence of the ligands on nanoparticles. The cellular-uptake study performed on A-549 cells demonstrated a significant enhancement in the uptake of dual-receptor targeted CSA nanoparticles than non-targeted and single-receptor targeted CSA nanoparticles. Further, CZT-loaded dual receptors targeted CSA nanoparticles also showed significantly lower IC₅₀ values (∼38 folds) than the CZT control against A-549 cells. Further, in-vivo histopathol. evaluations of dual receptor-targeted CSA nanoparticles have demonstrated better safety in Wistar rats. Moreover, its treatment on the Benzo(a)pyrene (B(a)P) induced lung cancer mice model has showed the enhanced anticancer efficacy of CZT with a prolonged survival rate.

Pillar-Layer Chiral MOFs as a Crystalline Platform for Circularly Polarized Luminescence and Single-Phase White-Light Emission was written by Gao, Peng-Fu;Jiang, Yu-Ying;Liu, Hui;Zhou, Meng-Shu;Li, Ting;Fu, Hong-Ru;Ma, Lu-Fang;Li, Dong-Sheng. And the article was included in ACS Applied Materials & Interfaces in 2022.Electric Literature of C20H18N2O2S The following contents are mentioned in the article:

The construction of circularly polarized luminescence (CPL) materials with high porosity and high rigidity is still challenging. Herein, we propose a chiral reticular chem. strategy to prepare the homochiral porous metal-organic frameworks (MOFs) as CPL-active materials. Two pairs of enantiomeric MOFs are synthesized through the self-assembly of chiral D/L-cam (DL-camphorates) and achiral fluorescent ligand TPB (1,2,4,5-tetra(pyridin-4-yl)benzene). The glum values of Cd-CMOF-D and Cd-CMOF-L were up to 0.010 and 0.009; the high glum values could be compared to those of the partially pure multicomponent self-assembly systems obtained by the complicated process. We further trace the generation and transfer of the hierarchical chirality from chiral mol. to 3D framework, demonstrating that the CPL was dominated by the original mol. chirality rather than the global chirality of the hierarchical structure. Moreover, the single-phase white-light materials with nearly ideal CIE coordinates (0.33, 0.33) were constructed through the introduction of dye emitters into Zn-CMOF (Zn-based chiral MOF). This work provided not only an insightful view of the chirality transfer and disappearance mechanism but also an efficient method for the preparation of the highly porous CPL materials.

And the article was included in Toxicology and Applied Pharmacology in 2022.Name: 3-(Benzo[d]thiazol-2-yl)-7-(diethylamino)-2H-chromen-2-one The following contents are mentioned in the article:

Quercetin (Que) exhibits excellent biol. activity; however, its clin. development is hindered owing to the poor water solubility In this study, Que. was loaded on polyvinyl caprolactam-polyvinyl acetate-polyethylene glycol graft copolymer (PVCL-PVA-PEG, Soluplus) micelles through a thin-film hydration process, and their tumor angiogenesis inhibition ability was investigated. The particle size of Soluplus-Que micelles was 55.3 ± 1.8 nm, and the micelles stayed stability within 9 mo. Soluplus-Que micelles can enhance the cell uptake of Que. and transport the micelles to intracellular lysosomes and mitochondria. The MTT assay results revealed that Soluplus-Que micelles enhanced the cytotoxicity of Que. on HUVEC cells. Furthermore, Soluplus-Que micelles inhibited migration and invasion of HUVEC cells, as well as inhibited the neovascularization of chick embryo allantoic membrane (CAM). The in vivo study revealed that Soluplus-Que micelles significantly inhibit the growth of H22 solid tumors, with low toxic side effects. Soluplus-Que inhibited the expression of CD31 (a marker of angiogenesis) and the PI3K/Akt/VEGF pathway in tumor tissues, indicating its potential to hold back tumor growth via the inhibition of angiogenesis. Our findings indicated that as a delivery system, Soluplus micelles demonstrate potential for the delivery of poorly soluble drugs for tumor treatment.

Coordination of rigidity modulation and targeting ligand modification on orally-delivered nanoparticles for the treatment of liver fibrosis was written by Yu, Yinglan;Xing, LiYun;Li, Lian;Wu, Jiawei;He, Jinhan;Huang, Yuan. And the article was included in Journal of Controlled Release in 2022.Category: thiazole The following contents are mentioned in the article:

Although the individual role of ligand modification or rigidity modulation on oral administration of nanoparticle (NP) has been investigated, how they mutually affect each other remains to be elucidated. Here, we fabricated different rigidity NP with or without surface decoration of FcBP, a neonatal Fc receptor domain-binding peptide. In vitro studies showed that, without FcBP modification, stiff NP had higher transcytosis efficiency across the epithelium than softer NP, due to the different endocytosis mechanisms, intracellular trafficking routes, and exocytosis rate. Notably, after FcBP modification, such difference was narrowed, in a manner that was more favorable for softer NP to “catch up” with stiff NP, suggesting ligand modification was more conducive to exert transcytosis-promoting efficacy on softer NP. In vivo experiments demonstrated that, for ligand-free NP, high rigidity was required for efficient oral absorption and liver distribution. Further FcBP modification decreased that “rigidity threshold”, and expanded the feasible rigidity range from stiff NP to softer NP. Upon oral administration, FcBP-modified dexamethasone-loaded softer NP achieved a therapeutic efficacy comparable with stiff NP on alleviating liver fibrosis. Collectively, our study highlighted the necessity of coordinating ligand modification and rigidity modulation for oral drug delivery. This study involved multiple reactions and reactants, such as 3-(Benzo[d]thiazol-2-yl)-7-(diethylamino)-2H-chromen-2-one (cas: 38215-36-0Category: thiazole).

Oral sorafenib-loaded microemulsion for breast cancer: evidences from the in-vitro evaluations and pharmacokinetic studies was written by Chaurawal, Nishtha;Misra, Charu;Abul Barkat, Harshita;Jatyan, Reena;Chitkara, Deepak;Barkat, Abul Md.;Sharma, Teenu;Singh, Bhupinder;Raza, Kaisar. And the article was included in Scientific Reports in 2022.Electric Literature of C20H18N2O2S The following contents are mentioned in the article:

Sorafenib tosylate (SFB) is a multikinase inhibitor that inhibits tumor growth and proliferation for the management of breast cancer but is also associated with issues like toxicity and drug resistance. Also, being a biopharmaceutical class II (BCS II) drug, its oral bioavailability is the other challenge. Henceforth, this report intended to encapsulate SFB into a biocompatible carrier with biodegradable components, i.e., phospholipid. The microemulsion of the SFB was prepared and characterized for the surface charge, morphol., micromeritics and drug release studies. The cell viability assay was performed on 4T1 cell lines and inferred that the IC50 value of sorafenib-loaded microemulsion (SFB-loaded ME) was enhanced compared to the naive SFB at the concentrations of about 0.75μM. More drug was available for the pharmacol. response, as the protein binding was notably decreased, and the drug from the developed carriers was released in a controlled manner. Furthermore, the pharmacokinetic studies established that the developed nanocarrier was suitable for the oral administration of a drug by substantially enhancing the bioavailability of the drug to that of the free SFB. The results bring forth the preliminary evidence for the future scope of SFB as a successful therapeutic entity in its nano-form for effective and safer cancer chemotherapy via the oral route.

Spatially targeting of tumor-associated macrophages and cancer cells for suppression of spontaneously metastatic tumor was written by Zhou, Minglu;Xie, Dandan;Zhou, Zhou;Li, Lian;Huang, Yuan. And the article was included in Nano Research in 2022.Safety of 3-(Benzo[d]thiazol-2-yl)-7-(diethylamino)-2H-chromen-2-one The following contents are mentioned in the article:

The interaction between cancer cells and M2 tumor-associated macrophages (M2-TAMs) facilitates tumor growth and metastasis. However, cancer cells and M2-TAMs have different spatial distribution patterns, which requires distinct drug delivery strategies. Herein, based on different tumor-penetrating ability of nanocarriers, we developed a combinatory strategy that consists of a TAMs-targeting liposome (alanine-alanine-asparagine (AAN)-Lip-regorafenib (Rego)) and a cancer cells-targeting copolymer (internalizing RGD modified with N-(2-hydroxypropyl) methacrylamide-doxorubicin (iRGD-HD)). Our study confirmed AAN-Lip-Rego accumulated at perivascular sites where M2-TAM is located, while iRGD-HD penetrated into deep site of tumor to enter cancer cells. Thereafter, we found iRGD-HD induced cancer cells undergoing immunogenic cell death to enhance tumor infiltration of CD8⁺ T cells. Meanwhile, AAN-Lip-Rego efficiently repolarized TAMs from M2 into M1 to alleviate tumor immunosuppression, thus reviving CD8⁺ T cells. Moreover, the repolarization of TAMs led to dramatic downregulation of prometastatic factors expressed on cancer cells. As a result, such combinatory approach elicited robust antitumor immune responses and generated considerable anti-tumor and anti-metastasis efficacy to markedly inhibit primary tumor and spontaneous lung metastasis.
