Abstract: Novel aromatic and heterocyclic thiazolyl thiourea compounds, pharameutical compositions including such, and methods for their use are disclosed. The compounds are effective agents for the treatment of HIV infection, including non-nucleoside inhibitor-resistant, and multi-drug resistant strains of HIV.

Abstract: Methods for increasing the elimination half-life of key metabolites such as d4T by administering an aryl phosphate derivative of d4T having an electron withdrawing substituent on the aryl group and an amino acid substituent on the phosphate group are described. A preferred aryl phosphate derivative of d4T is HI-113 (d4T-5′-[p-bromophenyl methoxyalaninyl phosphate]). The administration of HI-113 results in more prolonged systemic exposure to the key metabolites, Ala-d4T-MP and d4T, than administration of an equimolar dose of either metabolite. Each metabolite has a significantly longer elimination half life when formed in vivo from the administration of HI-113 than when the metabolite is administered directly.

Abstract: The invention provides compounds which inhibit reverse transcriptase (RT) and which inhibit replication of a retrovirus, such as human immunodeficiency virus-1 (HIV-1). The compound of the invention are phenoxyethyl-thiourea-pyridines. The invention additionally provides a method for inhibiting reverse transcriptase activity of a retrovirus, such as HIV-1, comprising contacting the retrovirus with a compound of the invention. The invention additionally provides a method for inhibiting replication of a retrovirus, such as HIV-1, comprising contacting the retrovirus with a compound of the invention.

Abstract: The present invention is directed to derivatives of piperidinylethyl, phenoxyethyl, and fluorophenethyl bromopyridyl thioureas, which have been found to be effective non-nucleoside inhibitors (NNRTI) of NNI-resistant and multi-drug resistant human immunodeficiency virus (HIV)-1 reverse transcriptase (RT). The present invention is further directed to methods of using the above derivatives to treat patients with NNI-resistant or multi-drug resistant human immunodeficiency virus (HIV)-1.
