  Synthesis of 1‐[(2‐Hydroxyethoxy)Methyl]‐6‐(5,6,7,8‐Tetrahydronaphthylmethyl‐1)Thymine as Novel Inhibitor against Drug‐Resistant HIV Mutants

  摘要：

  Synthesis of two new 1-[(2-hydroxycthoxy)methyl]-6-(5,6,7,8-tetrahydronaphthylmethyl-1)thymine derivatives 10a-b, as potent inhibitors against a mutant type of HIV, starting from thymine, is described. In the preparation of the corresponding 10a-b from compounds 9a-b, the three-step reaction via deprotection, hydrogenolysis, and hydrogenation was carried out in a one-pot procedure.

  palladium-catalyzed cross-coupling between a 6-iodo derivative (16) and terminal alkynes. Following the methods, 21 C-6 substituted analogues were synthesized. Among these, 6-(cyclohexylthio) (8), 6-phenoxy (13), and 6-benzyl (27) derivatives showed anti-HIV-1 (HTLV-IIIB) activity with EC50 values of 8.2, 85, and 23 microM, respectively. Preparation of C-5 substituted derivatives was based on either LTMP

• Activity of acyclic 6-(phenylselenenyl)pyrimidine nucleosides against human immunodeficiency viruses in primary lymphocytes

  Several 6-phenylselenenyl-substituted acyclouridine derivatives were prepared for evaluation as antiviral agents. Lithiation of the tert-butyldimethylsilyl-protected acyclonucleosides 4a-f with lithium diisopropylamide at -78-degrees-C, followed by reaction with diphenyl diselenide as an electrophile, and subsequent removal of the protecting group with tetra n-butylammonium fluoride gave 1-[(2-hydroxyethoxy)methyl]-6-(phenylselenenyl)uracils 6a-f in 50-70% overall yield. The potency and spectrum of activity of compounds 6a-f against HIV-1 in vitro was similar to HEPT (1), a related 6-phenylthio acyclonucleoside. However, whereas HEPT inhibited HIV-1 reverse transcriptase, the selenium-containing derivatives were ineffective, suggesting a different mechanism of action. Of significance was the finding that the 6-phenylselenenyl acyclonucleosides inhibited also HIV-2 in primary human lymphocytes.
