Synthesis, SAR studies, and pharmacological evaluation of 3-anilino-4-(3-indolyl) maleimides with conformationally restricted structure as orally bioavailable PKCβ-selective inhibitors
摘要:
Conformationally restricted 3-anilino-4-(3-indolyl)maleimide derivatives were designed and synthesized aiming at discovery of novel protein kinase C beta (PKC beta)-selective inhibitors possessing oral bioavailability. Among them, compounds having a fused five-membered ring at the indole 1,2-position inhibited PKC beta 2 with IC50 of nM-order and showed good oral bioavailability. One of the most potent compounds was found to be PKC beta-selective over other 6 isozymes and exhibited ameliorative effects in a rat diabetic retinopathy model via oral route. (c) 2006 Elsevier Ltd.

A chiral building block, (R)-2-(2,2-diethoxyethyl)-1,3-propanediol monoacetate was synthesized in high optical and chemical yields by lipase-catalyzed transesterification. From this compound, we synthesized chiral 3-substituted gamma-lactones and a new nucleoside with antiviral activity.

(EN) Compounds of formula (I) where one of R1 and R2 is -C(O)CH(CH(CH3)2)NH2 or -C(O)CH(CH(CH3)CH2CH3)NH2; the other of R1 and R2 is -C(=O)C3-C21 saturated or monounsaturated, optionally substituted alkyl; and R3 is OH or H; and pharmaceutically acceptable salts thereof have utility as enhanced bioavailability antivirals against herpes and retroviral infections.(FR) On décrit des composés de la formule (I) dans laquelle R1 ou R2 correspond à -C(O)CH(CH(CH3)2)NH2 ou -C(O)CH(CH(CH3)CH2CH3)NH2, tandis que l'autre élément correspond à un alkyle -C(=O)C3-C21 facultativement substitué, saturé ou monoinsaturé, et R3 correspond à OH ou H. On décrit également des sels pharmaceutiquement acceptables de ces composés, utiles comme antiviraux, à biodisponibilité renforcée, contre l'herpès et les infections par rétrovirus.
