The present invention provides compounds of formula I
1
and pharmaceutically acceptable salts thereof.
The formula I compounds inhibit the tyrosine kinase activity of growth factor receptors such as VEGFR-2, FGFR-1, thereby making them useful as anti-cancer agents. The formula I compounds are also useful for the treatment of other diseases associated with signal transduction pathways operating through growth factor receptors.

hydrogen bonding patterns. Compound 2 (orthorhombic, space group Pca21, Z = 8) forms polymeric N–H⋯N hydrogen-bonded zigzag tapes in the polar crystalstructure, with a significant twisting between the thiazole and pyridine rings. In contrast, the crystalstructure of 3 (monoclinic, space group P21/c, Z = 4) features nearly planar centrosymmetric N–H⋯N hydrogen-bonded dimers, which are laterally joined through

A series of N-substituted 2-aminobenzothiazoles, 2-aminothiazolopyridines, and 2-aminothiazoloquinolines were prepared by the cyclization of N,N'-disubstituted thiourea derivatives by bromine in acetic acid. The uv, ir and nmr data for these compounds are presented and discussed.

The reaction of [(p‐cymene)RuCl2]2 and [Cp*MCl2]2 (M = Rh/Ir) with benzoyl (2‐pyrimidyl) thiourea (L1) and benzoyl (4‐picolyl) thiourea (L2) led to the formation of cationic complexes bearing formula [(arene) M (L1)к2(N,S)Cl]+ and [(arene) M (L2)к2(N,S)Cl]+ [(arene) = p‐cymene, M = Ru, (1, 4); Cp*, M = Rh (2, 5) and Ir (3, 6)]. Precursor compounds reacted with benzoyl (6‐picolyl) thiourea (L3) affording

-yl) thiourea ligand was coordinated with Ni(II) and Co(II) perchlorate salts to isolate complexes. All the prepared compounds are deliberately investigated by all possible spectral tools. A comparative study for IR spectra reveals the neutral bidentate coordinating nature of the ligand towards the two metal ions. The UV/Vis spectra of the complexes display d-d transition bands proposed an octahedral
