Synthesis and in Vitro Antiprotozoal Activities of Water-Soluble, Inexpensive 3,7-Bis(dialkylamino)phenoxazin-5-ium Derivatives
摘要:
3,7-Bis(dialkylamino)phenoxazinium salts were synthesized and evaluated for in vitro activities against Plasmodium falciparum, Trypanosoma cruzi, T. brucei rhodesiense, and Leishmania donovani. Notably, the compounds showed potent antiprotozoal activities, especially against P. falciparum and T cruzi. The compounds with alkyl side chains less than three carbons in length possessed good activities with high selective indices.

A new series of unsymmetrical phenoxazinium chlorides, featuring a heterocyclic aromatic pi-bridge with dialkylamino donors, were evaluated in acetonitrile solution for third-order nonlinear optical properties at 532 nm using a Z-scan technique. The title compounds exhibit strong reverse saturable absorption and nonlinear refraction. The third-order nonlinear optical properties were obtained under nanosecond and picosecond laser beams. The nonlinear mechanism is revealed by the excited-state nonlinearity, as observed from a picosecond pump-probe response experiment for one of the compounds. They are potential nonlinear optical materials because they also have good solubility in polar solvents and good thermal stability. (C) 2011 Elsevier B. V. All rights reserved.
