Design, Synthesis, and Cytotoxic Activity of Novel Natural Arylsulfonamide-Inspired Molecules

Primary arylsulfonamide functional groups feature prominently in diverse pharmaceuticals. However, natural arylsulfonamides are relatively infrequent. In this work, two novel arylsulfonamide natural products were first synthesized, and then a series of novel molecules derived from natural arylsulfonamides were designed and synthesized, and their in vitro cytotoxic activities against A875, HepG2, and MARC145 cell lines were systematically evaluated. The results indicate that some of these arylsulfonamide derivatives exhibit significantly good cytotoxic activity against the tested cell lines compared with the control 5-fluorouracil (5-FU), such as compounds 10l, 10p, 10q, and 10r. In particular, the potential molecule 10q, containing a carbazole moiety, exhibited the highest inhibitory activity against all tested cell lines, with IC50 values of 4.19 ± 0.78, 3.55 ± 0.63, and 2.95 ± 0.78 μg/mL, respectively. This will offer the potential to discover novel drug-like compounds from the sparsely populated area of natural products that can lead to effective anticancer agents.

Structure-based virtual screening and optimization of modulators targeting Hsp90-Cdc37 interaction

Identification of novel Hsp90 inhibitors to disrupt Hsp90-Cdc37 protein-protein interaction (PPI) could be an alternative strategy to achieve Hsp90 inhibition. In this paper, a series of small molecules targeting Hsp90-Cdc37 complex are addressed and characterized. The molecules' key characters are determined by utilizing a structure-based virtual screening workflow, derivatives synthesis, and biological evaluation. Structural optimization and structure–activity relationship (SAR) analysis were then carried out on the virtual hit of VS-8 with potent activity, which resulted in the discovery of compound 10 as a more potent regulator of Hsp90-Cdc37 interaction with a promising inhibitory effect (IC50?=?27?μM), a moderate binding capacity (KD?=?40?μM) and a preferable antiproliferative activity against several cancer lines including MCF-7, SKBR3 and A549?cell lines (IC50?=?26?μM, 15?μM and 38?μM respectively). All the data suggest that compound 10 exhibits moderate inhibitory effect on Hsp90-Cdc37 and could be regard as a first evidence of a non-natural compound targeting Hsp90-Cdc37 PPI.

Discovery and synthesis of a potent sulfonamide ET(B) selective antagonist

The synthesis and structure-activity relationships of a series of sulfonamide endothelin antagonists are described. In the course of our modification studies, we discovered ET(B) selective antagonists. The most potent compound 15f displays IC50 values of 1.7 μM and 0.002 μM to ET(A) and ET(B) receptors, respectively. (C) 2000 Elsevier Science Ltd. All rights reserved.
