Abstrakt: The cellular toxicity and anti-human immunodeficiency virus type 1 (HIV-1) virucidal activity of four synthesized tyrosine-conjugated bile salt derivatives with high surfactant activities, namely di-iodo-deoxycholyltyrosine (DIDCT), di-iodo-chenodeoxycholyltyrosine (DICDCT), di-iodo-cholylglycyltyrosine (DICGT) and deoxycholyltyrosine (DCT), were evaluated and compared with either sodium deoxycholate or nonoxynol-9. DIDCT, DICDCT and DCT but not DICGT showed virucidal activity against three different laboratory-adapted strains of HIV-1 (RF, IIIB and MN). All the bile salt derivatives tested excluding DICGT were virucidal at a concentration as low as 10 ng/mL. DCT had the highest anti-HIV-1 virucidal potency, suggesting that monopeptide 7α,12α dihydroxy bile salt derivatives have the most potent antiviral activity. Complexing of iodine to the bile salt derivative (as in DICGT) decreases virucidal potency. [ABSTRACT FROM PUBLISHER]
