Synthesis and anticancer evaluation of bis(benzimidazoles), bis(benzoxazoles), and benzothiazoles
摘要:
Four classes of UK-1 analogues were synthesized and their cytotoxicity testing against human A-549, BFTC-905, RD, MES-SA, and HeLa carcinoma cell lines was determined. The results revealed that UK-1 and four of these analogues (15-18) are potent against the cancer cell lines. In particular, compound 16 is more potent than UK-1 against A-549 and HeLa cell lines, and compounds 15, 17, and 18 selectively exhibit potent cytotoxic activity against the BFTV-905 cells (IC50 9.6 PM), A-549 cells (IC50 6.6 mu M), and MES-SA cells (IC50 9.2 mu M),respectively.

Benzimidazole fungicides were among the early systemic fungicides developed and used for controlling a wide variety of plant diseases. During the course of our screening process for active compounds, two 2‐aryl benzimidazolesderivatives bearing sulfoxide group (6b and 6c) have been demonstrated to exhibit good inhibition activity against high‐resistant isolate of Botrytis cinerea compared with carbendazim

Light me up: Through the use of an imidazole motif it is possible to introduce a combined redox and proton‐transfermediator into single‐site rutheniumwater‐oxidation catalysts. With the complex (see picture), high turnover numbers and high initial turnover frequencies were attained with the mild oxidant [Ru(bpy)3]3+ (bpy=2,2′‐bipyridine).

Several novel compounds have been identified that inhibit the replication of hepatitis C virus in a replicon assay with EC50 values as low as 0.6 mu M. Lead compounds were modified to investigate the possible role that zinc binding may play in inhibitor efficacy. In addition, the structure-activity relationship was explored to increase inhibitor efficacy and possibly identify favorable interactions within the currently unknown inhibitor binding pocket. The rationale for inhibitor design and biological results are presented herein. (C) 2016 Elsevier Ltd. All rights reserved.
