A series of 1-benzyl-3-(imidazol-1-ylmethyl)indole derivatives 35-46 were prepared under mild reaction conditions and tested for their antifungal activity. Pharmacomodulation at N(1), C(2) and C(5) of the indole ring and at the level of the alkyl chain (R(1)) was carried out starting from the corresponding 3-acylindoles 6, 7 or 3-formylindoles 11-22. Target imidazolyl compounds 35-46 were obtained
To optimize the antitumor activity of oncrasin-1, a small molecule RNA polymerase II inhibitor, We evaluated 69 oncrasin-1 analogues for their cytotoxic activity against normal human epithelial cells and K-Ras mutant tumor cells. About 40 of those compounds were as potent as or more potent than oncrasin-1 in tumor cells and had a minimal cytotoxic effect on normal cells. Structure activity relationship analysis revealed that most of the active compounds contained either a hydroxymethyl group or an aldehyde group as a substitute at the 3-position of the indole. Both electron-donating and electron-withdrawing groups in the benzene ring were well tolerated. The hydroxymethyl compounds ranged from equipotent with to 100 times as potent as the corresponding aldehyde compounds. We tested three active analogues' effect on RNA, polymerase phosphorylation and found that they all inhibited phosphorylation of the C-terminal domain of RNA polymerase suggesting that the active compounds might act through the same mechanisms as oncrasin-1.
