Abel-Snape, Xavier;Wycich, Gina;Lautens, Mark research published 《 Synthesis of Indenes and Benzofulvenes via a Palladium-Catalyzed Three-Component Reaction》, the research content is summarized as follows. A palladium-catalyzed three-component domino reaction to access indene derivatives is reported. This reaction proceeds via the sequential formation of three bonds: the first two resulting from inter- and intramol. carbopalladation and the final bond arising from an attack by a terminating nucleophilic reagent. Modifying the starting tether on the iodoarene led to either indenes or benzofulvenes. Three termination variations were compatible with this sequence, which furnished products in moderate to good yields. The oxabicycle used in this work acts as an acetylene surrogate, which is revealed in a postcatalytic retro-Diels-Alder step. A diastereomerically enriched mixture of oxabicyclic derivatives allowed for preliminary results for the enantioselective synthesis of indenes.

Allegretti, Paul A.;Horton, Timothy M.;Abdolazimi, Yassan;Moeller, Hannah P.;Yeh, Benjamin;Caffet, Matthew;Michel, Guillermina;Smith, Mark;Annes, Justin P. research published 《 Generation of highly potent DYRK1A-dependent inducers of human β-Cell replication via Multi-Dimensional compound optimization》, the research content is summarized as follows. Small mol. stimulation of β-cell regeneration has emerged as a promising therapeutic strategy for diabetes. Although chem. inhibition of dual specificity tyrosine-phosphorylation-regulated kinase 1A (DYRK1A) is sufficient to enhance β-cell replication, current lead compounds have inadequate cellular potency for in vivo application. Herein, we report the clin. stage anti-cancer kinase inhibitor OTS167 as a structurally novel, remarkably potent DYRK1A inhibitor and inducer of human β-cell replication. Unfortunately, OTS167’s target promiscuity and cytotoxicity curtails utility. To tailor kinase selectivity towards DYRK1A and reduce cytotoxicity we designed a library of fifty-one OTS167 derivatives based upon a modeled structure of the DYRK1A-OTS167 complex. Indeed, derivative characterization yielded several leads with exceptional DYRK1A inhibition and human β-cell replication promoting potencies but substantially reduced cytotoxicity. These compounds are the most potent human β-cell replication-promoting compounds yet described and exemplify the potential to purposefully leverage off-target activities of advanced stage compounds for a desired application.

R.;Lun, Shichun;Luna, Giuseppe;Beh, Chau Chun;Payne, Alan D.;Foster, Neil;Bishai, William R.;Gunosewoyo, Hendra research published 《 Design, synthesis, and biological evaluation of novel arylcarboxamide derivatives as anti-tubercular agents》, the research content is summarized as follows. Our group has previously reported several indolecarboxamides exhibiting potent antitubercular activity. Herein, we rationally designed several arylcarboxamides based on our previously reported homol. model and the recently published crystal structure of the mycobacterial membrane protein large 3 (MmpL3). Many analogs showed considerable anti-TB activity against drug-sensitive (DS) Mycobacterium tuberculosis (M. tb) strain. Naphthamide derivatives 13c and 13d were the most active compounds in our study (MIC: 6.55, 7.11 microM, resp.), showing comparable potency to the first line anti-tuberculosis (anti-TB) drug ethambutol (MIC: 4.89 microM). In addition to the naphthamide derivatives, we also identified the quinolone-2-carboxamides and 4-arylthiazole-2-carboxamides as potential MmpL3 inhibitors in which compounds 8i and 18b had MIC values of 9.97 and 9.82 microM, resp. All four compounds retained their high activity against multidrug-resistant (MDR) and extensively drug-resistant (XDR) M. tb strains. It is worth noting that the two most active compounds 13c and 13d also exhibited the highest selective activity towards DS, MDR and XDR M. tb strains over mammalian cells [IC₅₀ (Vero cells) = 227 microM], indicating their potential lack of cytotoxicity. The four compounds were docked into the MmpL3 active site and were studied for their drug-likeness using Lipinski′s rule of five.

A simple Ni(cod)₂ and carbene mediated strategy facilitated the efficient catalytic cross-coupling of methoxyarenes with a variety of organoboron reagents. Directing groups facilitate the activation of inert C-O bonds in under-utilized aryl Me ethers enabling their adaptation for C-C cross-coupling reactions as less toxic surrogated to the ubiquitous haloarenes. The method reported enables C-C cross-coupling with readily available and economical arylboronic acid reagents, which was unprecedented and compared well with other organoboron reagents with similarly high reactivity. Extension to directing group assisted chemo-selective C-O bond cleavage and further application towards the synthesis of novel bifunctionalized biaryls was reported. Key to the success of this protocol was the use of directing groups proximal to the reaction center to facilitate the activation of the inert C-OMe bond.

Peripheral T-cell lymphoma (PTCL) is an aggressive tumor, rarely seen in pediatrics or adolescent and young adults (AYAs) so there is no upfront or relapsed standard of care. The authors describe a 16-year-old with PTCL, treated with chemotherapy and autologous stem cell transplant. Upon relapse, he received ifosfamide, carboplatin, etoposide, and radiation with durable remission of 4 years. Data in pediatric/AYA PCTL continue to lack an understanding of the biology and microenvironment, the differences to adult patients, and a lack of adequate therapy. Targeted therapy may improve outcomes for children and AYAs with refractory or relapsed PTCL.
