Selection, synthesis, and structure-activity relationship of tetrahydropyrido[4,3-d]pyrimidine-2,4-diones as human GnRH receptor antagonists

The present article describes a selection of a new class of small molecule antagonists for the h-GnRH receptor, their preparation, and evaluation in vitro. Three computational methods were combined into a consensus score, to rank order virtual templates. The top 5% of templates were further evaluated in silico and assessed for novelty and synthetic accessibility. The tetrahydropyrido[4,3-d]pyrimidine-2,4-dione core was selected for synthesis and evaluated in vitro. Using an array approach for analog design and synthesis, we were able to drive the binding below 10 nM for the h-GnRH receptor after two rounds of optimization.

The proportionality constant is the rate constant for the particular unimolecular reaction. the reaction rate is directly proportional to the concentration of the reactant. I hope my blog about 4644-61-5 is helpful to your research. category: piperidines

Novel 3-halo-2,2-disubstituted propanenitriles of formula STR1 wherein Z represents bromo or chloro and A, together with the carbon atom to which it is attached, represents a 5,6 or 7 membered saturated carbocyclic or heterocyclic ring, are useful as intermediates for preparing substituted pyrimido[1,2-a]indoles. The intermediates can be prepared by a novel process which comprises condensing a 2,2-disubstituted ethanenitrile with a dihalomethane in the presence of a non-nucleophilic strong base.

Development of Selective, Orally Active GPR4 Antagonists with Modulatory Effects on Nociception, Inflammation, and Angiogenesis

A novel, selective, and efficacious GPR4 antagonist 13 was developed starting from lead compound 1a. While compound 1a showed promising efficacy in several disease models, its binding to a H3 receptor as well as a hERG channel prevented it from further development. Therefore, a new round of optimization addressing the key liabilities was performed and led to discovery of compound 13 with an improved profile. Compound 13 showed significant efficacy in the rat antigen induced arthritis as well as in the hyperalgesia and angiogenesis model at a well-tolerated dose of 30 mg/kg.

Synthesis and antiproliferative activity of cyclic arylidene ketones: a direct comparison of monobenzylidene and dibenzylidene derivatives

Abstract To give further insight into the influence of the structural modifications of enones and dienones on their antiproliferative properties, 25 derivatives of enones: (E)-2-benzylidene-1-cyclohexanones, (E)-2-benzylidene-1-tetralones, (E)-2-benzylidene-1-indanone, and dienones: (E,E)-2,5- or 2,6-dibenzylidene-1-cyclanones, (E,E)-3,5-dibenzylidene-4-piperidones were synthesized using a newly developed “one-pot” synthetic method. Due to the fact that all of them have the same aryl substituents (phenyl or 4-chlorophenyl) in the arylidene moiety, it is possible to compare the relevant contribution of the single-point structural modifications (type of ring or N-substitution) on their potency on the basis of their IC 50 values. Their antiproliferative activity was evaluated against the following four human adherent cancer cell lines: HeLa, A431, A2780, and MCF7. The cytotoxicity screen has revealed that the dibenzylidene dienones in general dominate the monobenzylidene enones in this respect. The nitrogen-containing heterocyclic dienones at the same time displayed higher inhibitory properties toward these human carcinoma cell lines compared with their homocyclic dienone analogs. One of the eight newly prepared 4-piperidone derivatives, N-(gamma-oxobutyl)-(E,E)-3,5-bis(p-chlorobenzylidene)-4-piperidone is as potent a cell growth inhibitor (IC 50 of 0.438-1.409 muM) as the N-methyl-(E,E)-3,5-bis(p-chlorobenzylidene)-4-piperidone (IC 50 of 0.447-1.048 muM), one of the most active among the previously described compounds in this series. Catalytic hydrogen-transfer isomerization of compounds with two exocyclic benzylidene double bonds to derivatives with endocyclic double bonds results in the complete loss of antiproliferative activity. The structural modifications and 50 % inhibitory concentration (IC 50) values resulted in correlations which can promote the design of more potent derivatives of the 4-piperidone dienones.

Conversion of alcohols to alkyl esters and carboxylic acids using heterogeneous palladium-based catalysts

Disclosed are methods for synthesizing an ester or a carboxylic acid from an organic alcohol. To form the ester one reacts, in the presence of oxygen gas, the alcohol with methanol or ethanol. This reaction occurs in the presence of a catalyst comprising palladium and a co-catalyst comprising bismuth, tellurium, lead, cerium, titanium, zinc and/or niobium (most preferably at least bismuth and tellurium). Alternatively that catalyst can be used to generate an acid from that alcohol, when water is also added to the reaction mix.
