Synthesis and anti-HIV studies of 2- and 3-adamantyl-substituted thiazolidin-4-ones
摘要:
A series of novel thiazolidin-4-ones bearing a lipophilic adamantyl substituent at position 2 or 3 were synthesized. A majority of them showed a modest anti-HIV-1 activity, whereas 2-adamantan-1-yl-3-(4,6-dimethylpyrimidin-2-yl)-thiazolidin-4-one (8) was endowed with a remarkable antiviral potency (EC50 = 0.67 mu M). The new series of compounds (22-29) with an adamantyl moiety at the 3-position of the thiazolidinone ring showed good to modest anti-HIV-1 activity (EC50 = 1.0-11 mu M) but also pronounced cytostatic activity. For example 24, 26 and 29 showed an EC50 of 1.0-2.0 mu M, while the 50% effective concentrations for 23 and 28 were 7.8 and 11.0 mu M, respectively. X-ray studies and quantum chemical calculations revealed that the anti-HIV activity of the compounds strongly depends on their dipole moments and conformation of the thiazolidinones.

was observed with phthalimides 1, 3, and 6 and delivered stereospecifically the hexacyclic benzazepine products 12, 19, and 27, respectively. The lowest triplet states of 1−6 were characterized in several solvents upon direct and acetone-sensitized excitation. The intermolecular electron transfer from triethylamine and DABCO was studied, and the radical anions were observed. Electrochemical measurements

Threelibraries of adamantanederivatives were synthesized and evaluated for antiviral and antiproliferativeactivities against a broad variety of DNA and RNA viruses. Whereas none of the compounds exhibit antiviralactivity at subtoxic concentrations, antiproliferativeactivity was found against murine leukemia cells (L1210), human T‐lymphocyte cells (CEM), and cervix carcinoma cells (HeLa) for 4

intramolecular photochemical hydrogen atom abstraction in the solid state analyzed by X-ray crystallographic analyses. These analyses and solid-state photolyses showed that the parameters determining photochemical reactivity for typical carbonylcompounds in the solid state can also be extended to phthalimides. Only N-(2-adamantyl)phthalimide underwent a solid-state photochemicalreaction, which is the
