Synthetic nanoparticle-conjugated bisindoles and hydrazinyl arylthiazole as novel antiamoebic agents against brain-eating amoebae

Balamuthia mandrillaris and Naegleria fowleri are free-living amoebae that can cause life-threatening infections involving the central nervous system. The high mortality rates of these infections demonstrate an urgent need for novel treatment options against the amoebae. Considering that indole and thiazole compounds possess wide range of antiparasitic properties, novel bisindole and thiazole derivatives were synthesized and evaluated against the amoebae. The antiamoebic properties of four synthetic compounds i.e., two new bisindoles (2-Bromo-4-(di (1H-indo1-3-yl)methyl)phenol (denoted as Al) and 2-Bromo-4-(di (1H-indol-3-yl)methyl)-6-methoxyphenol (A2)) and two known thiazole (4-(3-Nitrophenyl) 2 (2 (pyridin-3-ylmethylene)hydrazinyl)thiazole (A3) and 4-(Biphenyl 4 yl) 2 (2 (1 (pyridin-4-yl)ethylidene)hydrazinyl)thiazole (A4)) were evaluated against B. mandrillaris and N. fowleri. The ability of silver nanoparticle (AgNPs) conjugation to enrich antiamoebic activities of the compounds was also investigated. The synthetic heterocyclic compounds demonstrated up to 53% and 69% antiamoebic activities against B. mandrillaris and N. fowleri respectively, while resulting in up to 57% and 68% amoebistatic activities, respectively. Antiamoebic activities of the compounds were enhanced by up to 71% and 51% against B. mandrillaris and N. fowleri respectively, after conjugation with AgNPs. These compounds exhibited potential antiamoebic effects against B. mandrillaris and N. fowleri and conjugation of synthetic heterocyclic compounds with AgNPs enhanced their activity against the amoebae.

Characterization of the Stereoselective P450 Enzyme BotCYP Enables the In Vitro Biosynthesis of the Bottromycin Core Scaffold

Bottromycins are ribosomally synthesized and post-translationally modified peptide natural product antibiotics that are effective against high-priority human pathogens such as methicillin-resistant Staphylococcus aureus. The total synthesis of bottromycins involves at least 17 steps, with a poor overall yield. Here, we report the characterization of the cytochrome P450 enzyme BotCYP from a bottromycin biosynthetic gene cluster. We determined the structure of a close BotCYP homolog and used our data to conduct the first large-scale survey of P450 enzymes associated with RiPP biosynthetic gene clusters. We demonstrate that BotCYP converts a C-terminal thiazoline to a thiazole via an oxidative decarboxylation reaction and provides stereochemical resolution for the pathway. Our data enable the two-pot in vitro production of the bottromycin core scaffold and may allow the rapid generation of bottromycin analogues for compound development.

I hope this article can help some friends in scientific research. I am very proud of our efforts over the past few months and hope to 7305-71-7 help many people in the next few years. Name: 2-Amino-5-methylthiazole.

Effects of pi-bridge units on the properties of donor-pi-acceptor type benzodithiophene-thienothiophene based polymers for organic solar cells

Conjugated donor (D)-pi-acceptor(A) cooligomers based on donor benzodithiophene(BDT) and acceptors thieno-thiophene(TT) are designed with furan, fusedthiophene, thiophene and thiazole 3t bridges. Effects of incorporation of the pi-bridges on structures and properties of oligomers and oligomer-fullerene composites are calculated and discussed. Maximum absorption wavelengths of newly designed oligomers are red shifted compared to that of the parent oligomer P1. The newly designed P2 -P5 oligomers have good light absorption efficiencies compared to that of P1. P4/PCBM and P5/PCBM blends have smaller intermolecular charge recombination rates than P1 and these two oligomers are expected to be more suitable for efficient solar cells.

Cardioprotective Effect of Novel Matrix Metalloproteinase Inhibitors

Background: We recently developed novel matrix metalloproteinase-2 (MMP-2) inhibitor small molecules for cardioprotection against ischemia/reperfusion injury and validated their efficacy in ischemia/reperfusion injury in cardiac myocytes. The aim of the present study was to test our lead compounds for cardioprotection in vivo in a rat model of acute myocardial infarction (AMI) in the presence or absence of hypercholesterolemia, one of the major comorbidities affecting cardioprotection. Methods: Normocholesterolemic adult male Wistar rats were subjected to 30 min of coronary occlusion followed by 120 min of reperfusion to induce AMI. MMP inhibitors (MMPI)-1154 and -1260 at 0.3, 1, and 3 mu mol/kg, MMPI-1248 at 1, 3, and 10 mu mol/kg were administered at the 25th min of ischemia intravenously. In separate groups, hypercholesterolemia was induced by a 12-week diet (2% cholesterol, 0.25% cholic acid), then the rats were subjected to the same AMI protocol and single doses of the MMPIs that showed the most efficacy in normocholesterolemic animals were tested in the hypercholesterolemic animals. Infarct size/area at risk was assessed at the end of reperfusion in all groups by standard Evans blue and 2,3,5-triphenyltetrazolium chloride (TTC) staining, and myocardial microvascular obstruction (MVO) was determined by thioflavine-S staining. Results: MMPI-1154 at 1 mu mol/kg, MMPI-1260 at 3 mu mol/kg and ischemic preconditioning (IPC) as the positive control reduced infarct size significantly; however, this effect was not seen in hypercholesterolemic animals. MVO in hypercholesterolemic animals decreased by IPC only. Conclusions: This is the first demonstration that MMPI-1154 and MMPI-1260 showed a dose-dependent infarct size reduction in an in vivo rat AMI model; however, single doses that showed the most efficacy in normocholesterolemic animals were abolished by hypercholesterolemia. The further development of these promising cardioprotective MMPIs should be continued with different dose ranges in the study of hypercholesterolemia and other comorbidities.

Synthesis of thiazole linked chalcones and their pyrimidine analogues as anticancer agents

A series of nine novel thiazole linked chalcones, (E)-3-(4-methyl-2-(4(trifluoromethyl)phenyl)thiazol-5-yl)-1-phenylprop-2-en-1-one derivatives 7-15 were synthesized. To establish the structure-activity relationship (SAR), furthermore, the corresponding, ring-closed pyrimidine analogs 17-23 were synthesized. The derivatives thus obtained were evaluated for their anti-cancer activity against three genetically different colorectal cancer (CRC) cell lines. Thiazole derivatives 7, 9, and10 showed anti-cancer activity with GI50 values ranging from 0.19 to 100 mu M. Importantly, compounds 7 and 10 outperformed the standard drug cisplatin in the tested cell lines and thus show promise for further optimization. Some of pyrimidine derivatives retain activity comparable to cisplatin in the HT-29 cell line, e.g. compounds 17 and 18 with IC50 of 25 mu M, however, none of these compounds demonstrated improved antiproliferative activity as compared with the starting thiazole, thus the enone linker was critical for obtaining more active compounds in this series.

Design, synthesis, biological evaluation, QSAR analysis and molecular modelling of new thiazol-benzimidazoles as EGFR inhibitors

Heterocyclic rings such as thiazole and benzimidazole are considered as privileged structures, since they constitute several FDA-approved drugs for cancer treatment. In this work, a new set of 2-(2-(substituted) hydrazinyl)-4-(1-methyl-1H-benzo[d]imidazol-2-yl) thiazoles 4a-q were designed as epidermal growth factor receptor (EGFR) inhibitors and synthesized using concise synthetic methods. The new target compounds have been evaluated in vitro for their suppression activity against EGFR TK. Compounds 4n, 4h, 4i, 4a and 4d exhibited significant potency in comparison with erlotinib which served as a reference drug (IC50, 71.67-152.59 nM; IC50 erlotinib, 152.59 nM). Furthermore, MTT assay revealed that compounds 4j, 4a, 4f, 4h, 4n produced the most promising cytotoxic potency against the human breast cancer cell line (MCF-7) (IC50; 5.96-11.91 mu M; IC50 erlotinib; 4.15 mu M). Compound 4a showed promising activity as EGFR TK inhibitor as well as anti-breast cancer agent. In addition, 4a induced apoptotic effect and cell cycle arrest at G2/M phase preventing the mitotic cycle in MCF-7 cells. Moreover, 4a upregulated the oncogenic parameters; caspase-3, p53, Bax/Bcl-2 as well as it inhibited the level of PARP-1 enzyme. QSAR study was carried out for the new derivatives and it revealed the goodness of the models. Furthermore, molecular docking studies represented the binding modes of the promising compounds in the active pocket of EGFR.

Synthesis, cytotoxic activities and molecular modeling studies of some 2-aminonaphtho[2,3-d][1,3]thiazole-4,9-dione derivatives

Quinones, especially 1,4-naphthoquinones, are one of the most significant and widely distributed phytochemical groups in nature. 1,4-Naphthoquinones and their synthetic derivatives are found to possess remarkable cytotoxic activities. In this study, a series of 2-aminonaphtho[2,3-d][1,3]thiazole-4,9-dione derivatives were synthesized and their structures were verified with spectral analysis. In vitro cytotoxic activities of the synthesized compounds were evaluated by using MTT assay against MKN-45 (Human Gastric cancer), MDA-MB-231 (Human Breast cancer) and HeLa (Human Cervical cancer) cell lines. Among the synthesized compounds, 3d inhibited MDA-MB-cell proliferation with an IC50 value of 0.276 mu M. Compound 3a inhibited HeLa and MKN-45 cell proliferation with IC50 values of 0.336 mu M and 8.769 mu M, respectively. Compound 3b inhibited HELA cell proliferation with an IC50 value of 0.269 mu M. Molecular docking results suggest that the ligands may bind to the hDNA TopoII beta binding pocket and partially exert their effects. These results propose that 2-aminonaphtho[2,3-d]thiazole-4,9-dion core has important biological effects and further explorations are worthwhile. (C)2020 ACG Publication. All right reserved.

Novel eIF4E/eIF4G protein-protein interaction inhibitors DDH-1 exhibits anti-cancer activity in vivo and in vitro

(E)-2-(2-(2,3-dibromo-4,5-dimethoxybenzylidene)hydrazinyl)-4-(3,4-difluorophenyl) thiazole (DDH-1) is novel small molecule compound synthesized in our previous work. This study found that DDH-1 could inhibit the proliferation of various human lung cancer cells. Particularly, the IC50 for A549 cells was 8.59 AM. Interestingly, we found that DDH-1 inhibits eIF4E/eIF4G interaction. The flow cytometry (FAGS) results have indicated that DDH-1 may induce G0/G1 cycle arrest by inhibiting the expression of Cyclin D1 and CDK4. DDH-1 may also cause apoptosis through the caspase-dependent pathway. Study of these mechanisms has shown that DDH-1 may prompt reactive oxygen species (ROS) generation, decrease the mitochondrial membrane potential (MMP), and stimulate DNA double-strand breaks (DSBs) in A549 cells. Study of the signal pathway has indicated that DDH-1 could activate JNK phosphorylation and inhibit ERK phosphorylation. Interestingly, NAC, which scavenges ROS, reversed the MMP decline, DNA damage, JNK phosphorylation activation, and ERK phosphorylation inhibition caused by DDH-1. Overall, these findings provide evidence that the eIF4E/eIF4G interaction inhibitors DDH-1 induces DNA damage and apoptosis in human lung cancer A549 cells. (C) 2020 Elsevier B.V.

Hydrogen Peroxide-Mediated Rapid Room Temperature Metal-Free C(sp(2))-H Thiocyanation of Amino Pyrazoles, Amino Uracils, and Enamines

A rapid metal- and additive-free room temperature method for C(sp(2))-H thiocyanation of aminopyrazoles, aminoisoxazole, aminoisothiazole, amino uracils, and aliphatic enamines has been developed in an aqueous medium using hydrogen peroxide as a benign oxidant and ammonium thiocyanate as a thiocyanating agent. On the other hand, the reaction of hydrogen peroxide and ammonium thiocyanate followed by one-pot addition of NaOH provides the corresponding disulfides in the case of amino azoles, and pyrimidine-fused 2-amino thiazoles were observed in the case of aminouracils. The salient features of this method are the use of an eco-friendly oxidant, reaction tunability to access different products, wide substrate scope, and good to very good yields.
