The palladium catalyzed cross-coupling reactions between 3-indoleboronic acids and vinyl triflates is a good method to introduce vinyl groups into the indole 3-position, e.g. I. The regioselectivity of the enolization of N-substituted-3-piperidones is far greater than previously reported. N-tosyl-3-indole boronic acids can be easily synthesized via mercuration-boronation method.

The palladium-catalyzed cross-coupling between 3-indoleboronic acids and vinyl triflates is an excellent method for the regioselective introduction of vinyl groups into the indole 3-position. The regioselectivity of the enolization of N-substituted 3-piperidones, as dictated by the nitrogen substituent, is far greater than previously reported. N-tosyl-3-indoleboronic acids can be easily synthesized using the mercuration-boronation method.

Palladium catalyzed cross-coupling reaction of 3-indolylboronic acid with 2,4-dichloropyrimidines proceeded regioselectively to yield indolyl- or bis(indolyl)pyrimidines in high yield, depending on the projection of 3-indolylboronic acid. The marine indole alkaloid meridianin D and an analog were synthesized via the palladium catalyzed cross-coupling reaction as a key step.

Kim, Jina published the artcileInsights of a Lead Optimization Study and Biological Evaluation of Novel 4-Hydroxytamoxifen Analogs as Estrogen-Related Receptor γ (ERRγ) Inverse Agonists, Product Details of C19H28BNO4, the publication is Journal of Medicinal Chemistry (2016), 59(22), 10209-10227, database is CAplus and MEDLINE.

We evaluated the in vitro pharmacol. as well as the absorption, distribution, metabolism, excretion, and toxicity (ADMET) properties of chem. entities that have not only shown to be highly selective agonists for ERRγ, but also exhibited enhanced pharmacokinetic profile than 3 (GSK5182). 6G and 10b had comparable potency to 3 and were far more selective for ERRγ over the ERRα, -β, and ERα. The in vivo pharmacokinetic profiles of 6g and 10b were further evaluated as they possessed superior in vitro ADMET profiles compared to the other compounds Addnl., we observed a significant increase of fully-glycosylated NIS protein, key protein for radioiodine therapy in anaplastic thyroid cancer (ATC), in 6g- or 10b-treated CAL62 cells, which indicated that these compounds could be promising enhancers for restoring NIS protein function in ATC cells. Thus, 6g and 10b possess advantageous drug-like properties and can be used to potentially treat various ERRγ-related disorders.

We herein report the structural optimization and structure-activity relationship studies of 5-(2,3-dihydro-1H-indol-5-yl)-7H-pyrrolo[2,3-d]pyrimidin-4-amine derivatives as a new class of receptor-interacting protein kinase 1 (RIPK1) inhibitors. Among all obtained RIPK1 inhibitors, I is the most active one. This compound potently inhibited RIPK1 with a binding affinity (K_D) of 0.004μM and an enzymic IC₅₀ value of 0.011μM and also showed good kinase selectivity. It could efficiently protect cells from necroptosis and attenuate the necrotic cell death of vascular endothelial cells induced by tumor cells both in vitro and in vivo. Importantly, I exhibited excellent antimetastasis activity in the exptl. B16 melanoma lung metastasis model. It also displayed favorable pharmacokinetic properties. Collectively, I could be a promising agent for preventing tumor metastasis.
