The present invention relates to novel heterocyclic compounds that inhibit phosphodiesterase type 4 (PDE4). The compounds are useful for treating inflammatory conditions, diseases of the central nervous system and insulin resistant diabetes , (formula I) wherein P is selected from the group consisting of bond, oxygen, sulfur and NR1; wherein P1 is selected from the group consisting of hydrogen, halogen atom, -OR1, -S(O)mR1, -C(O)R1, formly amine, nitro and -NRxRy. R2 is selected from the group consisting of hydrogen, halogen, substituted or unsubstituted alkyl, substituted or unsubstituted cycloalkyl, CN, -CH=CR3R3. The ring 'A' is selected from the group consisting of substituted or unsubstituted aryl ring, and optionally substituted saturated or unsaturated five to seven membered heterocyclic ring containing one or more heteroatoms selected from the group consisting of O, S, and NR1; wherein R1, Rx, Ry and R3 are as defined in the description.
Design, synthesis and biological evaluation of substituted aminopyridazin-3(2 H )-ones as G0/G1-phase arresting agents with apoptosis-inducing activities
series of aminopyridazin-3(2H)-one derivatives has been designed and synthesized. Their antiproliferative activities were evaluated against three human cancer cell lines (SH-SY5Y human neuroblastoma, K562 human myelogenous leukemia and AGS gastric cancer cell lines) using the MTT assay. The preliminary activity test displayed that compound 8a exhibited comparable activities against all test cells with
