ABSTRACT:

The present invention is concerned with novel compounds of formula (I) having HIV replication inhibiting properties. The invention further relates to methods for preparing such novel compounds, pharmaceutical compositions comprising said novel compounds as well as the use as a medicine of said compounds.
Compounds structurally related to the present novel compounds are disclosed in the prior art. DE-2,121,694, published on Nov. 25, 1971, discloses a number of s-triazines useful as anti-inflammatory, tranquillising, antiviral, antispasmodic, hypo-glycaemic, diuretic, and vasodilating agents, and for modifying adreno-cortico hormone secretion. DE-2,226,474, published on Feb. 22, 1973, discloses diamino- 1,3,5-triazine derivatives with hormone secretion-increasing activity, and anti-inflammatory effect. Substituted triazines having diuretic activity were published in Guioca,
Ann. Pharm. Fr.,
31:283 -292 (1973). A number of 2,4-diamino-triazines were prepared in Kelarev V.I. et al.,
Khim. GeterotsikL. Soedin.,
1392-1397 (1987) and Kelarev V.I. et al.,
Khim. Geterotsikl. Soedin.,
1395-1399 (1992). The preparation of 2-amino-4-benzyl-6-o-toluidino-s-triazine was described in Yuki Y. et al.,
Kobunshi Kagaku,
26: 141-147 (1969). The use of aralkylguanamines, in particular 2-amino-4-anilino-6-benzyl-s-triazine, for the manufacture of resins is disclosed in U.S. Pat. No. 2,817,614, granted Dec. 24, 1957.
Unexpectedly, it has now been found that the compounds of formula (I) effectively inhibit the replication of the Human Immunodeficiency Virus (HIV) and consequently may be useful for the treatment of individuals infected by HIV.
