Zhang, Xing Xing published the artcileDiscovery of 4-((E)-3,5-dimethoxy-2-((E)-2-nitrovinyl)styryl)aniline derivatives as potent and orally active NLRP3 inflammasome inhibitors for colitis, Name: 2-Methylbenzoic acid, the publication is European Journal of Medicinal Chemistry (2022), 114357, database is CAplus and MEDLINE.

A series of pterostilbene derivatives I [R¹ = tert-Bu, Ph, 2-furyl, etc] were designed and synthesized based on previous SAR, leading to discovery of new effective NLRP3 inflammasome inhibitors with metabolic stability. Among them, the most effective compound I [R¹ = 2-furyl] showed high inhibitory efficacy (against IL-1 ¦Â: IC₅₀ = 1.23¦ÌM) and almost no toxicity (against IL-1 b: IC₅₀ > 100¦ÌM). Further mechanism studies have showed that compound I [R¹ = 2-furyl] directly targets the NLRP3 and affects the assembly of inflammasomes to inhibit the activation of NLRP3 inflammasomes. More importantly, in vitro experiments show that compound I [R¹ = 2-furyl] has a significant therapeutic effect on DSS-induced colitis in mice with good metabolic stability to liver microsomes (t_1/2 = 138.6 min). This research encourages the further development of more effective NLRP3 inflammasome inhibitors based on this chem. scaffold.

Tadros, Joseph published the artcileA Comparison of Immobilised Triphenylphosphine and 1-Hydroxybenzotriazole as Mediators of Catch-and-Release Acylation Under Flow Conditions, Safety of 2-Methylbenzoic acid, the publication is Chemistry – An Asian Journal (2022), 17(5), e202101308, database is CAplus and MEDLINE.

Herein, a comparative study of immobilized triphenylphosphine (PS-PPh₃) and 1-hydroxybenzotriazole (PS-HOBt) to mediate amide couplings under continuous flow was described. Compared to Appel-type amidations (PS-PPh₃), the developed ‘catch-and-release’ approach (PS-HOBt) afforded near-quant. amide conversions. Utilizing this strategy, sulfonyl chloride amenability enabled facile access to an expanded library of sulfonate and sulfonamides. Post-constructional peptide modification was also demonstrated, affording two N¦Â-functionalized pentapeptides in high yields and purities. In contrast to frequently utilized coupling agents, the PS-HOBt resin could be recycled six times without a reduction in efficacy or regeneration requirements.

Bertuzzi, Giulio published the artcileOrganocatalytic Enantioselective Construction of Conformationally Stable C(sp²)-C(sp³) Atropisomers, COA of Formula: C8H8O2, the publication is Journal of the American Chemical Society (2022), 144(2), 1056-1065, database is CAplus and MEDLINE.

Nonbiaryl atropisomers are mols. defined by a stereogenic axis featuring at least one nonarene moiety. Among these, scaffolds bearing a conformationally stable C(sp²)-C(sp³) stereogenic axis have been observed in natural compounds; however, their enantioselective synthesis remains almost completely unexplored. Herein we disclose a new class of chiral C(sp²)-C(sp³) atropisomers obtained with high levels of stereoselectivity (up to 99% ee) by means of an organocatalytic asym. methodol. Multiple mol. motifs could be embedded in this class of C(sp²)-C(sp³) atropisomers, showing a broad and general protocol. Exptl. data provide strong evidence of the conformational stability of the C(sp²)-C(sp³) stereogenic axis (up to t_1/2²⁵?^¡ãC >1000 y) in the obtained compounds and show kinetic control over this rare stereogenic element. This, coupled with d. functional theory calculations, suggests that the observed stereoselectivity arises from a Curtin-Hammett scenario establishing an equilibrium of intermediates. Furthermore, the exptl. investigation led to evidence of the operating principle of central-to-axial chirality conversions.

Jia, Jingwen published the artcileA cobalt covalent organic framework: a dual-functional atomic-level catalyst for visible-light-driven C-H annulation of amides with alkynes, Synthetic Route of 118-90-1, the publication is Journal of Materials Chemistry A: Materials for Energy and Sustainability (2022), 10(21), 11514-11523, database is CAplus.

Herein, a synthesis of a dual-functional cobalt covalent organic framework (CoCOF-SYNU-1) for visible-light-driven C-H annulation of amides with alkynes was reported. An at.-level cobalt center ensures the occurrence of powerful chelation with amides and subsequent precise C-H activation, while the photoactive covalent organic framework was responsible for absorbing visible light to accelerate the catalytic cycle. In the presence of CoCOF-SYNU-1, visible-light-driven regioselective [4 + 2] C-H annulation proceeded smoothly, delivering a wide range of isoquinolin-1(2H)-one derivatives I [R¹ = n-Pr, n-Bu, Ph, etc.; R² = H, n-Pr, trimethylsilyl, etc.; R³ = H, 6-Me, 8-I, etc.; Q = 8-quinolyl] with high efficiency. Significantly, due to the inherent heterogeneous nature and good stability of CoCOF-SYNU-1, the reaction exhibited excellent catalyst recyclability and practicability.

Hoque, Emdadul Md published the artcileIridium-Catalyzed Ligand-Controlled Remote para-Selective C-H Activation and Borylation of Twisted Aromatic Amides, Name: 2-Methylbenzoic acid, the publication is Angewandte Chemie, International Edition (2022), 61(27), e202203539, database is CAplus and MEDLINE.

A method of para-selective borylation of fully twisted aromatic amides ArCONBoc₂ is described, yielding boronamides 4-pinBC₆H_nX_4-nCONBoc₂ (X = alkyl, alkoxy, aryl, halo, CN). The borylation proceeded via an unprecedented substrate-ligand distortion between the twisted aromatic amides and a newly designed ligand framework, 4,5-diaza-9H-fluorene (defa) that is different from the traditionally used ligand (dtbpy) for the C-H borylation reactions. The designed ligand defa has led to the development of a new type of catalytic system that shows excellent para selectivity for a range of aromatic amides. Moreover, the designed ligand has shown excellent reactivity and selectivity for a range of heterocyclic aromatic amides. The identification of key transition states and intermediates using the DFT computations associated with the three regio-isomeric pathways revealed that the most efficient catalytic pathway with the defa ligand leads to the para borylation while in the case of bpy the borylation at the para and meta sites compete.

Freitas, Brendan T. published the artcileExploring Noncovalent Protease Inhibitors for the Treatment of Severe Acute Respiratory Syndrome and Severe Acute Respiratory Syndrome-Like Coronaviruses, Related Products of catalysis-chemistry, the publication is ACS Infectious Diseases (2022), 8(3), 596-611, database is CAplus and MEDLINE.

Over the last 20 years, both severe acute respiratory syndrome coronavirus-1 and severe acute respiratory syndrome coronavirus-2 have transmitted from animal hosts to humans causing zoonotic outbreaks of severe disease. Both viruses originate from a group of betacoronaviruses known as subgroup 2b. The emergence of two dangerous human pathogens from this group along with previous studies illustrating the potential of other subgroup 2b members to transmit to humans has underscored the need for antiviral development against them. Coronaviruses modify the host innate immune response in part through the reversal of ubiquitination and ISGylation with their papain-like protease (PLpro). To identify unique or overarching subgroup 2b structural features or enzymic biases, the PLpro from a subgroup 2b bat coronavirus, BtSCoV-Rf1.2004, was biochem. and structurally evaluated. This evaluation revealed that PLpros from subgroup 2b coronaviruses have narrow substrate specificity for K48 polyubiquitin and ISG15 originating from certain species. The PLpro of BtSCoV-Rf1.2004 was used as a tool alongside PLpro of CoV-1 and CoV-2 to design 30 novel noncovalent drug-like pan subgroup 2b PLpro inhibitors that included determining the effects of using previously unexplored core linkers within these compounds Two crystal structures of BtSCoV-Rf1.2004 PLpro bound to these inhibitors aided in compound design as well as shared structural features among subgroup 2b proteases. Screening of these three subgroups 2b PLpros against this novel set of inhibitors along with cytotoxicity studies can provide new directions for pan-coronavirus subgroup 2b antiviral development of PLpro inhibitors.
