A palladium(II)-catalyzed enantioselective α-alkylation of azlactones with nonconjugated alkenes is described. The reaction employs a chiral BINOL-derived phosphoric acid as the source of stereoinduction, and a cleavable bidentate directing group appended to the alkene to control the regioselectivity and stabilize the nucleopalladated alkylpalladium(II) intermediate in the catalytic cycle. A wide range of azlactones were found to be compatible under the optimal reaction conditions to afford products bearing α,α-disubstituted α-amino-acid derivatives with high yields and high enantioselectivity.

A series of novel 4-substituted-phenoxy-benzamide derivatives bearing an aryl cycloaliphatic amine moiety were synthesized and evaluated for antiproliferative activity against SW620, HT29 and MGC803 cancer cell lines in vitro. The pharmacological data demonstrated that the majority of target compounds exhibited moderate efficacy in HT29 and MGC803 cell lines. Compound 10c showed promising inhibition of hedgehog (Hh) signaling pathway in an Hh-related assay. In addition, the superposition pattern of 10c showed a good fit for a pharmacophoric model generated by Hh inhibitors and provided a basis for further structural optimization.

In this study, a series of novel N-(piperidine-4-yl)benzamide derivatives was designed, synthesized, and evaluated for antitumor activity. Some compounds were found to have potent antitumor activity. In particular, compound 47 showed the most potent biological activity against HepG2 cells, with an IC50 value of 0.25 μm. Western blot analysis demonstrated that compound 47 inhibited the expression of cyclin B1 and p-Rb and enhanced the expression of p21, p53, Rb, and phospho-adenosine monophosphate-activated protein kinase (p-AMPK). Further, cell cycle arrest was observed by flow cytometry (FCM). In summary, compound 47 was screened to have potential activity for the treatment of hepatocarcinoma via the induction of cell cycle arrest by a p53/p21-dependent pathway.

There is continuing interest in the discovery and development of new κ opioid receptor antagonists. We recently reported that N-substituted 3-methyl-4-(3-hydroxyphenyl)piperazines were a new class of opioid receptor antagonists. In this study, we report the syntheses of two piperazine JDTic-like analogues. Evaluation of the two compounds in an in vitro [35S] GTPγS binding assay showed that neither compound showed the high potency and κ opioid receptor selectivity of JDTic. A library of compounds using the core scaffold 21 was synthesized and tested for their ability to inhibit [35S]GTPγS binding stimulated by the selective κ opioid agonist U69,593. These studies led to N-[(1S)-1-{[(3S)-4-(3-hydroxyphenyl)-3- methylpiperazin-1-yl]methyl}-2-methylpropyl]-4-phenoxybenzamide (11a), a compound that showed good κ opioid receptor antagonist properties. An SAR study based on 11a provided 28 novel analogues. Evaluation of these 28 compounds in the [35S]GTPγS binding assay showed that several of the analogues were potent and selective κ opioid receptor antagonists.
