This paper describes the synthesis and the antiviral activities of dimeric compounds derived from homo and asymmetric combinations of N-1 propynyloxymethyl analogues 1a,b of MKC-442, an N-1 4-iodobenzyloxymethyl analogue of TNK-651 5, potent contraceptive norgestrel and AZT. They were obtained by Sonogashira reaction, 'click' chemistry or Pd-catalyzed oxidative coupling. The iodo precursor 5 turned out as a potent compound against wild type and mutated HIV-1 virus. All dimeric compounds showed lower activity against HIV-1 than MKC-442, except the asymmetric dimer of AZT and 1a which showed an activity comparable to MKC-442.

Abstract
This paper describes the synthesis and the antiviral activities of dimeric compounds derived from homo and asymmetric combinations of N-1 propynyloxymethyl analogues 1a,b of MKC-442, an N-1 4-iodobenzyloxymethyl analogue of TNK-651 5, potent contraceptive norgestrel and AZT. They were obtained by Sonogashira reaction, 'click' chemistry or Pd-catalyzed oxidative coupling. The iodo precursor 5 turned out as a potent compound against wild type and mutated HIV-1 virus. All dimeric compounds showed lower activity against HIV-1 than MKC-442, except the asymmetric dimer of AZT and 1a which showed an activity comparable to MKC-442.
