Ravu, Ranga Rao;Jacob, Melissa R.;Khan, Shabana I.;Wang, Mei;Cao, Liang;Agarwal, Ameeta K.;Clark, Alice M.;Li, Xing-Cong research published 《 Synthesis and Antifungal Activity Evaluation of Phloeodictine Analogues》, the research content is summarized as follows. The phloeodictine-based 6-hydroxy-2,3,4,6-tetrahydropyrrolo[1,2-a]pyrimidinium structural moiety with an n-tetradecyl side chain at C-6 has been demonstrated to be a new antifungal template. Thirty-four new synthetic analogs with modifications of the bicyclic tetrahydropyrrolopyrimidinium skeleton and the N-1 side chain have been prepared and evaluated for in vitro antifungal activities against the clin. important fungal pathogens including Cryptococcus neoformans ATCC 90113, Candida albicans ATCC 90028, Candida glabrata ATCC 90030, Candida krusei ATCC 6258, and Aspergillus fumigatus ATCC 90906. Nineteen compounds showed antifungal activities against the aforementioned five fungal pathogens with min. inhibitory concentrations (MICs) in the range 0.88-10μM, and all were fungicidal with min. fungicidal concentrations (MFCs) similar to the resp. MIC values. Three compounds were especially active against C. neoformans ATCC 90113 with MIC/MFC values of 1.0/1.0, 1.6/1.6, and 1.3/2.0μM but exhibited low cytotoxicity with an IC₅₀ > 40μM against the mammalian Vero cells. The structure and antifungal activity relationship indicates that synthetic modifications of the phloeodictines can afford analogs with potent antifungal activity and reduced cytotoxicity, necessitating further preclin. studies of this new class of antifungal compounds

Gary;Trotter, B. Wesley research published 《 Discovery of MK-4688: an Efficient Inhibitor of the HDM2-p53 Protein-Protein Interaction》, the research content is summarized as follows. Identification of low-dose, low-mol.-weight, drug-like inhibitors of protein-protein interactions (PPIs) is a challenging area of research. Despite the challenges, the therapeutic potential of PPI inhibition has driven significant efforts toward this goal. Adding to recent success in this area, we describe herein our efforts to optimize a novel purine carboxylic acid-derived inhibitor of the HDM2-p53 PPI into a series of low-projected dose inhibitors with overall favorable pharmacokinetic and phys. properties. Ultimately, a strategy focused on leveraging known binding hot spots coupled with biostructural information to guide the design of conformationally constrained analogs and a focus on efficiency metrics led to the discovery of MK-4688 (compound 56), a highly potent, selective, and low-mol.-weight inhibitor suitable for clin. investigation.

PipaonFernandez, Nahiane;Gaube, Gregory;Woelk, Kyla J.;Burns, Mathias;Hruszkewycz, Damian P.;Leitch, David C. research published 《 Palladium-Catalyzed Direct C-H Alkenylation with Enol Pivalates Proceeds via Reversible C-O Oxidative Addition to Pd(0)》, the research content is summarized as follows. A direct tandem C-O/C-H activation approach to C-C bond formation using palladium catalysis was reported. This reaction combines C-O oxidative addition at enol pivalates e.g., I with concerted metalation-deprotonation of functionalized heterocycles e.g., II to achieve base-free direct C-H alkenylation. Preliminary mechanistic studies revealed that the C-O oxidative addition to Pd(0) is reversible under these conditions and C-H activation occurs directly from the Pd(II) C-O oxidative addition products e.g., III. In situ ³¹P NMR spectroscopy further revealed that the (Cy₃P)₂Pd-(alkenyl)(OPiv) species is a major catalyst resting state during the reactions.

A set of new substituted dienes were synthesized from betulinic acid by its oxidation to 30-oxobetulinic acid followed by the Wittig reaction. Cytotoxicity of all compounds was tested in vitro in eight cancer cell lines and two noncancer fibroblasts. Almost all dienes were more cytotoxic than betulinic acid. Four compounds had IC₅₀ below 5μmol/L; I and II were selected for studies of the mechanism of action. Cell cycle anal. revealed an increase in the number of apoptotic cells at 5 x IC₅₀ concentration, where activation of irreversible changes leading to cell death can be expected. Both I and II led to the accumulation of cells in the G0/G1 phase with partial inhibition of DNA/RNA synthesis at 1 x IC₅₀ and almost complete inhibition at 5 x IC₅₀. Interestingly, compound II at 5 x IC₅₀ caused the accumulation of cells in the S phase. Higher concentrations of tested drugs probably inhibit more off-targets than lower concentrations Mechanisms disrupting cellular metabolism can induce the accumulation of cells in the S phase. Both compounds I and II trigger selective apoptosis in cancer cells via intrinsic pathway, which we have demonstrated by changes in the expression of the crucial apoptosis-related protein. Pharmacol. parameters of derivative I were superior to II, therefore I was the finally selected candidate for the development of anticancer drug.

Petruncio, Greg;Elahi-Mohassel, Synah;Girgis, Michael;Paige, Mikell research published 《 Copper-catalyzed sp³-sp³ cross-coupling of turbo grignards with benzyl halides》, the research content is summarized as follows. The aromatic ring in benzyl halides and sulfonates imparts unique reactivity at the benzylic carbon atom. Photoredox sp³-sp³ cross-coupling proved ineffective for coupling p-methoxybenzyl chloride (PMBCl), leading to a new strategy for the sp³-sp³ cross-coupling of benzyl halides and sulfonates. This strategy involved LiCl-accelerated synthesis of a Grignard reagent followed by a copper-catalyzed cross-coupling. The conditions worked well for PMBCl due to its exceptional reactivity but other benzyl bromides or sulfonates reacted poorly.

Here, we demonstrate that substitution of the benzyl groups of glucosyl imidate donors with trifluoromethyl results in a substantial increase in 1,2-cis-selectivity when activated with TMS-I in the presence of triphenylphosphine oxide. Stereoselectivity is dependent on the number of trifluoromethyl groups (4-trifluoromethylbenzyl vs 3,5-bis-trifluoromethylbenzyl). Particularly encouraging is that we observe high 1,2-cis-selectivity with reactive alc. acceptors.
