In order to discover more promising antifungalagents, a series of aminoguanidine derivatives of N-arylsulfonyl-3-acylindoles (5a–r) were prepared and evaluated in vitro for their antifungalactivities against seven phytopathogenic fungi. Especially compounds 5n and 5o exhibited more potent antifungalactivities than or comparable to hymexazol, a commercially available agricultural fungicide at the
In order to find compounds with superior anti human immunodeficiency virus type 1 (HIV-1) activity, twelve simple N-arylsulfonylindoles (3a—l) were synthesized and preliminarily evaluated as HIV-1 inhibitors in vitro for the first time. Several compounds demonstrated significant anti-HIV-1 activity, especially N-(3-nitrobenzene)sulfonyl-6-methylindole (3h) and N-(3-nitrobenzene)sulfonylindole (3i) showed the highest anti-HIV-1 activity with EC50 values of 0.26 and 0.74 μg/ml, and TI values of 543.78 and >270.27, respectively.

An efficientsynthesis of N‐arylsulfonylindoles fromindoles and arylsulfonylchlorides in the presence of triethylbenzylammonium chloride (TEBA) and NaOH at room temperature is described.
In continuation of our program aimed at the discovery and development of compounds with superior anti-human immunodeficiency virus type 1 (HIV-1) activity, 21N-arylsulfonyl-3-acetylindole analogs (2a-u) were synthesized and preliminarily evaluated as HIV-1 inhibitors in vitro. Among of all the analogs, several compounds exhibited significant anti-HIV-1 activity, especially N-phenylsulfonyl-3-acetyl-6-methylindole (2j) and N-(p-ethyl)phenylsulfonyl-3-acetyl-6-methylindole (2n) showed the most potent anti-HIV-1 activity with EC50 values of 0.36 and 0.13 mu g/mL, and TI values of >555.55 and 791.85, respectively. It demonstrated that introduction of the acetyl group at the 3-position of N-arylsulfonyl-6-methylindoles could generally lead to the more potent analogs. (C) 2010 Elsevier Ltd. All rights reserved.
