ESI-MS of your synthesized compounds confirmed the corresponding M + one peak.In-vitro HIV-1 RT screeningIn-vitro reports of your exam compounds (5a-o), showed weak to average activity towards HIV-1 RT (Table 1). One of the analyzed compounds, five compounds (5d, 5f, 5h, 5n and 5o) showed over fifty Natural Product Like Compound Library site enzyme inhibition at examined 100 M concentration. Substitutions with electron donating teams especially on the para place of the phenyl ring increased the efficiency versus HIV-1 RT, such as p-methyl substituted compound 5d (fifty two.forty six inhibition) exhibited one.five occasions stronger as compared with un-substituted a person (5a) (34.32 inhibition). In the same way, p-methoxy substituted compound 5f is a lot more strong (56.23 inhibition) as compared with the m-substituted compound 5e (44.21 inhibition).
