Synthesis and biological activity of new derivatives of 6-chloro-5-((4-chlorophenyl) diazenyl) pyrimidine-2, 4-diamine and 4-chloro-6-methoxy-N, N-dimethylpyrimidin-2-amine
Journal Title: IOSR Journal of Pharmacy (IOSRPHR) - Year 2014, Vol 4, Issue 1
Abstract
6-chloro-5-((4-chlorophenyl) diazenyl) pyrimidine-2, 4-diamine and 4-chloro-6-methoxy-N,N-dimethylpyrimidin-2-amine has been used as precursors for the synthesis of new pyrimidine derivatives, employing Suzuki cross-coupling reaction. Thus, treatment of pyrimidine derivative with various arylboronic acids in the presence of palladium tetraacetate, PhP3 and Na2CO3 in refluxing n-propanol afforded the target compounds. The synthesis was supported by spectroanalytical techniques. The synthesized compounds have been screened for their inhibitory activity against some microbial, the results were showed that among gram positive isolates only (1/10) isolates of S. aureus and (3/10) isolates of S. saprophyticaus were sensitive for compound 13, while (1/10) isolates of S. aureus and (1/10) isolates of S.saprophyticaus were sensitive for compound 4. All isolates of S. pyogenes were resisting to all compounds, among gram negative bacterial isolates only (2/10) isolates of E. coli and (1/10) isolates of K. pneumoniae were sensitive to compound 4. Concerning the antifungal effects of compounds 3, 4, 5, 13, 14, 15 the results revealed that, all C. albicans and C. glabrata isolate were resist these compounds
