Abstract
A group of myristic acid analogs, designed as alternative substrates for N-myristoyltransferase (NMT), were evaluated against human immunodeficiency virus (HIV), hepatitis B virus (HBV) and duck hepatitis B virus (DHBV) in vitro. Antiviral potency was increased when S or O was substituted for -CH2- in myristic acid and selectivity was affected by the presence and position of the heteroatoms and phenyl groups. A correlation was established among anti-HIV activity, Log P and Log D7.4 and between anti-HIV activity and carbonyl-heteroatom interatomic distances in the myristoyl analogs. 12-Thioethyldodecanoic acid 6 was moderately active (EC50 = 9.37 microM) against HIV-infected T4-lymphocytes (CEM-SS cell line), and it exhibited in vitro activity (EC50 = 17.8 microM) against HBV-producing 2.2.15 cell cultures derived from a human hepatoblastoma cell line (Hep G2). 12-Methoxydodecanoic acid 1 exhibited in vitro activity (EC50 = 20-30 microM) against hepatitis B in the HBV DNA-transfected 2.2.15 cell line. At a concentration of 10 microg/ml, none of the fatty acids significantly inhibited the replication of DHBV in infected hepatocytes.Entities:
