Cyclin-dependent kinases (CDKs) are promising therapeutic targets for cancer therapy. Herein, we describe our efforts toward the discovery of a series of 5-chloro-N4-phenyl-N2-(pyridin-2-yl)pyrimidine-2,4-diamine derivatives as dual CDK6 and 9 inhibitors. Intensive structural modifications lead to the identification of compound 66 as the most active dual CDK6/9 inhibitor with balancing potency against these two targets and good selectivity over CDK2. Further biological studies revealed that compound 66 was directly bound to CDK6/9, resulting in suppression of their downstream signaling pathway and inhibition of cell proliferation by blocking cell cycle progression and inducing cellular apoptosis. More importantly, compound 66 significantly inhibited tumor growth in a xenograft mouse model with no obvious toxicity, indicating the promising therapeutic potential of CDK6/9 dual inhibitors for cancer treatment. Therefore, the above results are of great importance in the development of dual CDK6/9 inhibitors for cancer therapy.

To develop novel therapeutic agents with anticancer activities, two series of novel 7-amino-[1,2,4]triazolo[4,3-f]pteridinone, and 7-aminotetrazolo[1,5-f]pteridinone derivatives were designed and synthesized. All compounds were tested for anti-proliferative activities against five cancer cell lines. The structure-activity relationships (SARs) studies were conducted through the variation in two regions, the moiety of A ring and the terminal aniline B on pteridinone core. 1-Methyl-1,2,4-triazole derivative L7 with 2,6-dimethylpiperazine showed the most potent antiproliferative activity against A549, PC-3, HCT116, MCF-7 and MDA-MB-231 cell lines with IC50 values of 0.16 μM, 0.30 μM, 0.51 μM, 0.30 μM, and 0.70 μM, respectively. Combined with the results of the molecular docking and enzymatic studies, the PLK1 was very likely to be one of the drug targets of compound L7. Furthermore, to clarify the anticancer mechanism of compound L7, further explorations in the bioactivity were conducted. The results showed that compound L7 obviously inhibited proliferation of A549 cell lines, induced a great decrease in mitochondrial membrane potential leading to apoptosis of cancer cells, suppressed the migration of tumor cells, and arrested G1 phase of A549 cells.

, p. 603 - 617 (2016/07/06)
A series of 1-phenyl-3/4-[4-(aryl/heteroaryl/alkyl-piperazine1-yl)-phenyl-urea derivatives (29–42) were designed, synthesized and evaluated for their anticonvulsant activity by using maximal electroshock (MES), subcutaneous pentylenetetrazole (scPTZ) seizure tests. The acute neurotoxicity was checked by rotarod assay. Most of the test compounds were found effective in both seizure tests. Compound 30 (1-{4-[4-(4-chloro-phenyl)-piperazin-1-yl]-phenyl}-3-phenyl-urea) exhibited marked anticonvulsant activity in MES as well as scPTZ tests. The phase II anticonvulsant quantification study of compound 30 indicates the ED50value of 28.5?mg/kg against MES induced seizures. In addition, this compound also showed considerable protection against pilocarpine induced status epilepticus in rats. Seizures induced by 3-mercaptopropionic acid model and thiosemicarbazide were significantly attenuated by compound 30, which suggested its broad spectrum of anticonvulsant activity. Interestingly, compound 30 displayed better antidepressant activity than standard drug fluoxetine. Moreover, compound 30 appeared as a non-toxic chemical entity in sub-acute toxicity studies.

, p. 1092 - 1099 (2015/02/19)
A series of alkyl/aryl/heteroaryl piperazine derivatives (37-54) were designed and synthesized as potential anticonvulsant agents. The target compounds are endowed with satisfactory physicochemical as well as pharmacokinetic properties. The synthesized compounds were screened for their in vivo anticonvulsant activity in maximal electroshock (MES) and subcutaneous pentylenetetrazole (sc-PTZ) seizure tests. Further, neurotoxicity evaluation was carried out using rotarod method. Structure activity relationship studies showed that compounds possessing aromatic group at the piperazine ring displayed potent anticonvulsant activity. Majority of the compounds showed anti-MES activity whereas compounds 39, 41, 42, 43, 44, 50, 52, and 53 exhibited anticonvulsant activity in both seizure tests. All the compounds except 42, 46, 47, and 50 did not show neurotoxicity. The most active derivative, 45 demonstrated potent anticonvulsant activity in MES test at the dose of 30 mg/kg (0.5 h) and 100 mg/kg (4 h) and also delivered excellent protection in sc-PTZ test (100 mg/kg) at both time intervals. Therefore, compound 45 was further assessed in PTZ-kindling model of epilepsy which is widely used model for studying epileptogenesis. This compound was effective in delaying onset of PTZ-evoked seizures at the dose of 5 mg/kg in kindled animals and significantly reduced oxidative stress better than standard drug phenobarbital (PB). In result, compound 45 emerged as a most potent and safer anticonvulsant lead molecule.

A new series possessing [1,2,3]triazolo[4,5-d]pyrimidine scaffold was synthesized and biologically evaluated for potential antiproliferative activity. Fourteen compounds were selected for in vitro anticancer assay over a panel of 60 cell lines at National Cancer Institute (NCI), USA. The most sensitive cell lines to the synthesized compounds were leukemia (K-562 and SR), nonsmall cell lung cancer HOP-92, and melanoma MDA-MB- 435. Compounds 12 and 24 exerted broad spectrum activity against most cell panel, while compounds 14, 21, and 23 exhibited effectiveness toward specific cell lines belong to different tumor subpanels. Accordingly, SAR, COMPARE analyses, and in silico ADME profiling were discussed for the target compounds. In addition, compounds 11 and 22 exerted good FGFR3 inhibitory activity with 58.8 and 46.7% at 100 μM, respectively. Taken as a whole, the present study revealed that the new series can be considered as promising lead for further development of more potent anticancer agents as well as FGFR3 kinase potential inhibitors.

The analogs of N-[4-(piperazin-1-yl)phenyl]cinnamamide were designed and synthesized by molecular hybridization approach in which part C of the designed molecule was linked through amide and carbamate functionality that improves the physicochemical properties and govern the pharmacokinetic and pharmacodynamic behavior. The systematic modification was done around the Part C to explore the structure activity relationship of antitubercular cinnamamide. All 52 compounds were evaluated for its antitubercular activity against Mycobacterium tuberculosis (M. tb) using Resazurin microtitre plate assay (REMA). Compound 11g with trifluoromethyl substitution exhibited good antitubercular activity of 3.125 μg/ml. The synthesized N-[4-(piperazin-1-yl)phenyl]cinnamamide derivatives showed promising activity against M. tb.
