Korvorapun, Korkit published the artcileLate-Stage Diversification by Selectivity Switch in meta-C-H Activation: Evidence for Singlet Stabilization, Product Details of C8H6ClF3, the publication is ACS Catalysis (2020), 10(1), 435-440, database is CAplus.

The full control of site selectivity in C-H activation is paramount for the programmed late-stage functionalization of structurally complex structures. During the past decade, directing groups have revolutionized mol. synthesis in terms of ortho-selective C-H activation. In sharp contrast, a selectivity switch that guides the typical ortho- to remote meta-C-H activation has thus far proven elusive. Herein, we describe the realization of such a concept for a robust selectivity control in ruthenium catalysis. The distal C-H transformation was guided by key mechanistic insights into the mild, synergistic action of carboxylates and phosphines in ruthenium(II) catalysis. Our findings allowed remote selectivity in broadly effective late-stage diversification of structurally complex drugs and natural product mols., tolerating sensitive fluorescent dyes, drugs, lipids, peptides, nucleosides and carbohydrates.

Abdeen, Sanofar published the artcileSulfonamido-2-arylbenzoxazole GroEL/ES Inhibitors as Potent Antibacterials against Methicillin-Resistant Staphylococcus aureus (MRSA), Related Products of chlorides-buliding-blocks, the publication is Journal of Medicinal Chemistry (2018), 61(16), 7345-7357, database is CAplus and MEDLINE.

Extending from a study we recently published examining the anti-trypanosomal effects of a series of GroEL/ES inhibitors based on a pseudo-sym. bis-sulfonamido-2-phenylbenzoxazole scaffold, here, we report the antibiotic effects of asym. analogs of this scaffold against a panel of bacteria known as the ESKAPE pathogens (Enterococcus faecium, Staphylococcus aureus, Klebsiella pneumoniae, Acinetobacter baumannii, Pseudomonas aeruginosa, and Enterobacter species). While GroEL/ES inhibitors were largely ineffective against K. pneumoniae, A. baumannii, P. aeruginosa, and E. cloacae (Gram-neg. bacteria), many analogs were potent inhibitors of E. faecium and S. aureus proliferation (Gram-pos. bacteria – EC₅₀ values of the most potent analogs were in the 1-2 μM range). Furthermore, even though some compounds inhibit human HSP60/10 biochem. functions in vitro (IC₅₀ values in the 1-10 μM range), many of these exhibited moderate to low cytotoxicity to human liver and kidney cells (CC₅₀ values >20 μM).

A review. Peptidomimetics are a privileged class of pharmacophores that exhibit improved physicochem. and biol. properties. Solid-phase synthesis is a powerful tool for gaining rapid access to libraries of mols. from small mols. to biopolymers and also is widely used for the synthesis of peptidomimetics. Small mols. including heterocycles serve as a core for hundreds of drugs, including peptidomimetic mols. This review covers solid-phase synthesis strategies for peptidomimetics mols. based on heterocycles.

Broumidis, Emmanouil published the artcileA one-pot, two-step synthesis of 3-deazacanthin-4-ones via sequential Pd-catalyzed Suzuki-Miyaura and Cu-catalyzed Buchwald-Hartwig reactions, Category: chlorides-buliding-blocks, the publication is Tetrahedron Letters (2017), 58(27), 2661-2664, database is CAplus.

3-Deazacanthin-4-one and nine analogs, including the 8-aza analog, were prepared rapidly and in high yields from 8-iodoquinolones and 2-chloro(het)arylboronic acids. The strategy involves construction of the central B ring via sequential Pd-catalyzed Suzuki-Miyaura C-C and Cu-catalyzed Buchwald-Hartwig C-N coupling reactions [e.g., Suzuki reaction of iodoquinolone I with (2-chlorophenyl)boronic acid followed by intramol. Buchwald-Hartwig → II (90%)].

Canthin-6-one (I; R¹ = R² = H) and nine analogs including the naturally occurring 9-methoxycanthin-6-one (I; R¹ = OMe, R² = H) and amaroridine (I; R¹ = H, R² = OMe) are prepared rapidly and in high yields via a convergent “non-classical” strategy that focuses on construction of the central ring B. The strategy relies on concomitant Pd-catalyzed Suzuki-Miyaura C-C coupling followed by a Cu-catalyzed C-N coupling that can be achieved either stepwise or in a new one-pot protocol starting from the appropriate 8-bromo-1,5-naphthyridine.

Karpina, V. R. published the artcileThe synthesis and biological assessment of [[1,2,4]triazolo[4,3-a]pyridine-3-yl]acetamides with an 1,2,4-oxadiazole cycle in positions 6, 7 and 8, SDS of cas: 6313-54-8, the publication is Zhurnal Organichnoi ta Farmatsevtichnoi Khimii (2019), 17(1), 28-35, database is CAplus.

A novel method was developed for the synthesis of 32 analogs of 2-[(1,2,4-oxadiazol-5-yl)-[1,2,4]triazolo[4,3-a]pyridine-3-yl]acetamides and biol. assessment was conducted. A convenient scheme for the synthesis of the title compounds started from com. available 2-chloropyridine-3-/4-/5-carboxylic acids with amidoximes to form the corresponding 2-chloro-[1,2,4-oxadiazol-5-yl]pyridines then followed by the hydrazinolysis with an excess of hydrazine hydrate. The process continued via the ester formation with the pyridine ring closure, followed by amide formation. A series of new 2-[6/7/8-(1,2,4-oxadiazol-5-yl)[1,2,4]triazolo[4,3-a]pyridine-3-yl]acetamides were obtained in good yields and their structures were proved by the method of ¹H NMR spectroscopy. The prognosis and study of their pharmacol. activity were also conducted. The synthetic approach of obtaining the representatives of 2-[(1,2,4-oxadiazol-5-yl)-[1,2,4] triazolo[4,3-a]pyridine-3-yl]acetamides previously unknown can be used as an applicable method for the synthesis of diverse functionalized [1,2,4]triazolo[4,3-a]pyridine derivatives
