2-Aminobenzoxazole ligands of the hepatitis C virus internal ribosome entry site
摘要:
2-Aminobenzoxazoles have been synthesized as ligands for the hepatitis C virus (HCV) internal ribosome entry site (IRES) RNA. The compounds were designed to explore the less basic benzoxazole system as a replacement for the core scaffold in previously discovered benzimidazole viral translation inhibitors. Structure-activity relationships in the target binding of substituted benzoxazole ligands were investigated. (C) 2014 Elsevier Ltd. All rights reserved.

Novel compounds of the general formula ##STR1## wherein Z represents a substituted lower alkyl radical; each of R.sub.1 and R.sub.2 is hydrogen atom, a lower alkyl or a substituted lower alkyl identical with or different from Z and the functional groups NO.sub.2 and NR.sub.1 R.sub.2 can occupy all ring positions in relation to OZ, with the exception that if Z is .beta.-hydroxyethyl, --NO.sub.2 is in the 4 position and --N(R.sub.1)(R.sub.2) is in the 2 position then either R.sub.1 or R.sub.2 is other than hydrogen. The novel compounds are for dyeing human hair in a variety of yellow shades. The compounds of formula (I) may be used as aqueous or water-alcohol solutions to form dye compositions for dyeing human hair.
