Novel Small Molecule Inhibitors of Choline Kinase Identified by Fragment-Based Drug Discovery

Choline kinase alpha (ChoKalpha) is an enzyme involved in the synthesis of phospholipids and thereby plays key roles in regulation of cell proliferation, oncogenic transformation, and human carcinogenesis. Since several inhibitors of ChoKalpha display antiproliferative activity in both cellular and animal models, this novel oncogene has recently gained interest as a promising small molecule target for cancer therapy. Here we summarize our efforts to further validate ChoKalpha as an oncogenic target and explore the activity of novel small molecule inhibitors of ChoKalpha. Starting from weakly binding fragments, we describe a structure based lead discovery approach, which resulted in novel highly potent inhibitors of ChoKalpha. In cancer cell lines, our lead compounds exhibit a dose-dependent decrease of phosphocholine, inhibition of cell growth, and induction of apoptosis at low micromolar concentrations. The druglike lead series presented here is optimizable for improvements in cellular potency, drug target residence time, and pharmacokinetic parameters. These inhibitors may be utilized not only to further validate ChoKalpha as antioncogenic target but also as novel chemical matter that may lead to antitumor agents that specifically interfere with cancer cell metabolism.

We¡¯ll also look at important developments in the pharmaceutical industry because understanding organic chemistry is important in understanding health, medicine, the role of 130345-50-5, and how the biochemistry of the body works.Safety of Quinoxaline-6-carbaldehyde

One-pot 2-aryl/vinylindole synthesis consisting of a ruthenium-catalyzed hydroamination and a palladium-catalyzed heck reaction using 2-chloroaniline

A one-pot synthesis of 2-aryl- and 2-vinylindoles based on a ruthenium-catalyzed hydroamination and a palladium-catalyzed intramolecular Heck reaction is reported. The ruthenium-catalyzed addition reaction was applied to terminal as well as internal alkynes. Intramolecular Heck reactions of the resulting 2-chloroanilino enamines were achieved using an in situ generated palladium complex derived from an N-heterocyclic carbene. Georg Thieme Verlag Stuttgart.

Palladium/di-1-adamantyl-n-butylphosphine-catalyzed reductive carbonylation of aryl and vinyl halides

A general and efficient palladium-catalyzed reductive carbonylation with low catalyst loadings (0.5 mol % Pd or below) has been developed. The formylation of aryl and heteroaryl bromides proceeds smoothly in the presence of palladium/di-1-adamantyl-n-butylphosphine at ambient pressure of synthesis gas to afford the corresponding aromatic aldehydes in good yields and excellent selectivity. In addition, vinyl halides react under similar conditions to form alpha,beta-unsaturated aldehydes in good yield.
