Synthesis and Pharmacological Evaluation of 1-Oxo-2-(3-piperidyl)-1,2,3,4-tetrahydroisoquinolines and Related Analogues as a New Class of Specific Bradycardic Agents Possessing If Channel Inhibitory Activity

A series of 1-oxo-2-(3-piperidyl)-1,2,3,4-tetrahydroisoquinolines and related analogues were prepared and evaluated for their bradycardic activities in isolated right atrium and in anesthetized rats. (± )-6,7-Dimethoxy-2-{1- [3-(3,4-methylenedioxyphenoxy)propyl]-3-piperidyl}-1,2,3, 4-tetrahydroisoquinoline (4) was chosen as a lead, and structural modifications were performed on the tetrahydroisoquinoline ring and the terminal aromatic ring. The modifications on the tetrahydroisoquinoline ring revealed that the 1-oxo-1,2,3,4-tetrahydroisoquinoline ring system was optimum structure for both in vitro potency and in vivo efficacy. Furthermore, methoxy, ethoxy, and methoxycarbonyl groups were identified as preferable substituents on the terminal aromatic ring. One of the 1-oxo-1,2,3,4-tetrahydroisoquinoline derivatives, (R)-10a, was further evaluated for its bradycardic activity and inhibitory activity against If currents. Compound (R)-10a demonstrated potent bradycardic activity in rats with minimal influence on blood pressure after oral administration. The compound also showed inhibition of If currents (IC50 = 0.32 muM) in guinea pig pacemaker cells.

Synthesis and antibacterial activity of cinnamaldehyde acylhydrazone with a 1,4-benzodioxan fragment as a novel class of potent ss-Ketoacyl-acyl carrier protein synthase III (FabH) inhibitor

Fatty acid biosynthesis is essential for bacterial survival. ss-Ketoacyl-acyl carrier protein (ACP) synthase III (FabH), is a particularly attractive antibacterial target, since it is central to the initiation of fatty acid biosynthesis. Three series of 21 cinnamaldehyde acylhydrazone derivatives, A3-9, B3-9, and C3-9, were synthesized and evaluated for FabH-inhibitory activity. Compound B6 showed the most potent biological activity against Escherichia coli, Pseudomonas aeruginosa, Staphylococcus aureus, and Bacillus subtilis (minimum inhibitory concentrations (MICs) values: 1.56-3.13mug/mL) and was comparable with the positive control. Docking simulation by positioning compound B6 in the FabH structure active site was performed to explore the possible binding model.

Small Molecule Microarray Based Discovery of PARP14 Inhibitors

Poly(ADP-ribose) polymerases (PARPs) are key enzymes in a variety of cellular processes. Most small-molecule PARP inhibitors developed to date have been against PARP1, and suffer from poor selectivity. PARP14 has recently emerged as a potential therapeutic target, but its inhibitor development has trailed behind. Herein, we describe a small molecule microarray-based strategy for high-throughput synthesis, screening of >1000 potential bidentate inhibitors of PARPs, and the successful discovery of a potent PARP14 inhibitor H10 with >20-fold selectivity over PARP1. Co-crystallization of the PARP14/H10 complex indicated H10 bound to both the nicotinamide and the adenine subsites. Further structure?activity relationship studies identified important binding elements in the adenine subsite. In tumor cells, H10 was able to chemically knockdown endogenous PARP14 activities.

An Efficient and Selective Nickel-Catalyzed Direct N-Alkylation of Anilines with Alcohols

Herein, we developed an efficient and selective nickel-catalyzed monoalkylation of various primary alcohols with aryl and heteroaryl amines together with diols and amino alcohol derivatives. Notably, the catalytic protocol consisting of an earth-abundant and non-precious NiBr2/L1 system enables the transformations in the presence of hydroxyl, alkene, nitrile, and nitro functionalities. As a highlight, we have demonstrated the alkylation of diamine, intramolecular cyclization to N-heterocycles, and functionalization of complex vitamin E, an (±)-alpha-tocopherol derivative. Preliminary mechanistic studies revealed the participation of a benzylic C-H bond in the rate-determining step.

Synthesis and biological activity of novel carbacyclins having bicyclic substituents on the omega-chain

A number of carbacyclins having bicyclic substituents on the omega-chain have been synthesized and tested for antiplatelet aggregation activity in vitro (against collagen-induced aggregation of rat platelet), for reduction of systemic blood pressure in vivo (ability to reduce the blood pressure in anesthetized rat by iv injection), and for cytoprotective activity (protection against ethanol-induced rat gastric lesion). The most effective compound for each activity was [3aS-[2E,3aalpha,4alpha(3R),5beta,6aalpha]]-5-[hexahydro-5-hydroxy-4-[3-hydroxy-3-(2- indanyl)-1-propynyl]-2(1H)-pentalenylidene]pentanoic acid (compound 11a), while some 1,4-benzodioxan analogues had selectivity for organ-protective activity, and indan analogues showed selectivity in their antiaggregation activity.

Phenylcinnamides as novel antimitotic agents

Compound 8H is a phenylcinnamide that induces G2/M-phase cell cycle arrest and cell death in cancer cell lines. Here we show that 8H exerts its cytotoxic activity through disruption of microtubule dynamics in vitro and in cell culture. A series of cinnamide derivatives were synthesized and evaluated, and several new compounds were identified that improve on the activity of the parent compound, with IC50 values for induction of cell death ranging from 1 to 10 muM. Notably, these compounds retain potency in the HL-60/VCR leukemia cell line, which is resistant to antimitotic cancer drugs vincrisitine and paclitaxel through up-regulation of P-glycoprotein drug efflux pumps. As P-glycoprotein expression is often responsible for drug resistance in cancer and the exclusion of compounds from the central nervous system, 8H and its derivatives merit further examination as potential antimitotic therapeutics, specifically for brain cancers and cancers that are resistant to standard antimitotic agents.

Structure-activity relationship study of selective benzimidazole-based inhibitors of Cryptosporidium parvum IMPDH

Cryptosporidium parasites are important waterborne pathogens of both humans and animals. The Cryptosporidium parvum and Cryptosporidium hominis genomes indicate that the only route to guanine nucleotides is via inosine 5?-monophosphate dehydrogenase (IMPDH). Thus the inhibition of the parasite IMPDH presents a potential strategy for treating Cryptosporidium infections. A selective benzimidazole-based inhibitor of C. parvum IMPDH (CpIMPDH) was previously identified in a high throughput screen. Here we report a structure-activity relationship study of benzimidazole-based compounds that resulted in potent and selective inhibitors of CpIMPDH. Several compounds display potent antiparasitic activity in vitro.
