Thiazolothiazepine inhibitors of HIV-1 integrase

A series of thiazolothiazepines were prepared and tested against purified human immunodeficiency virus type-1 integrase (HIV-1 IN) and viral replication. Structure-activity studies reveal that the compounds possessing the pentatomic moiety SC(O)CNC(O) with two carbonyl groups are in general more potent against purified IN than those containing only one carbonyl group. Substitution with electron-donating or -withdrawing groups did not enhance nor abolish potency against purified IN. By contrast, compounds with a naphthalene ring system showed enhanced potency, suggesting that a hydrophobic pocket in the IN active site might accommodate an aromatic system rather than a halogen. The position of sulfur in the thiazole ring appears important for potency against IN, as its replacement with an oxygen or carbon abolished activity. Further extension of the thiazole ring diminished potency. Compounds 1, 19, and 20 showed antiviral activity and inhibited IN within similar concentrations. These compounds inhibited IN when Mn2+ or Mg2+ was used as cofactor. None of these compounds showed detectable activities against HIV-1 reverse transcriptase, protease, virus attachment, or nucleocapsid protein zinc fingers. Therefore, thiazolothiazepines are potentially important lead compounds for development as inhibitors of IN and HIV replication.

Thiazepine inhibitors of HIV-1 integrase

The present invention discloses non-catechol compounds, such as thiazolothiazepines, and analogs and derivatives thereof, which are anti-integrase inhibitors. The compounds, which are useful as treatments for HIV disease, include compounds (I), (II), (III), or pharmaceutically acceptable salts thereof wherein A is thiazole, benzene, naphthalene, pyridine, pyrimidine, pyrazine, or quinoline; R is one or more of H, halogen, lower alkyl, lower alkoxy, NO2, lower ester or carboxylic acid; X—Y is CH2—S, S—CH2, CH2—O, CH2—S(O). S(O)—CH2, CH2—CH2, CH2—CH2—CH2, or CH2—CH2—CH2—CH2; R4 is H or hydroxy; R5 is H, phenyl, or alkylamine; W is S or O; and R6 is H, substituted or unsubstituted alkyl or amine; and Z is S, O, CH2, CH2CH2, or C═O.

Isothiazolones

Isothiazolones having the general structure STR1 where A is a monocyclic or bicyclic ring which may contain up to 3 heteroatoms selected from O, S, and N; R1 and R2 are substituent groups such as alkyl, alkoxy, hydroxy, nitro, cyano, amino, and carboxy; and R5 is alkyl, cycloalkyl, phenyl, and Het. The isothiazolones are useful as anti-retroviral agents, anti-inflammatory agents, and anti-atherosclerotic agents.
