Kim, Minsoo published the artcileStructure activity relationship exploration of 5-hydroxy-2-(3-phenylpropyl)chromones as a unique 5-HT_2B receptor antagonist scaffold, SDS of cas: 939-99-1, the publication is Bioorganic & Medicinal Chemistry Letters (2020), 30(21), 127511, database is CAplus and MEDLINE.

Antagonists for the serotonin receptor 2B (5-HT_2B) have clin. applications towards migraine, anxiety, irritable bowl syndrome, and MDMA abuse; however, few selective 5-HT_2B antagonists have been identified. Previous studies from these labs identified a natural product, 5-hydroxy-2-(2-phenylethyl)chromone (5-HPEC, 2) as the first non-nitrogenous ligand for the 5-HT_2B receptor. Studies on 5-HPEC optimization led to the identification of 5-hydroxy-2-(3-phenylpropyl)chromone (5-HPPC, 3), which showed a tenfold improvement in binding affinity over 2 at 5-HT_2B. This study aimed to further improve receptor pharmacol. of this unique scaffold. Guided by mol. modeling studies modifications at the C-3′ and C-4′ positions of 3 were made to probe their effects on ligand binding affinity and efficacy. Among the derivatives synthesized 5-hydroxy-2-(3-(3-cyanophenyl)propyl)chromone (5-HCPC, 3d) showed the most promise with a multifold improvement in binding affinity (pK_i = 7.1 ± 0.07) over 3 with retained antagonism.

Hamada, Shohei published the artcileChemoselective Oxidation of p-Methoxybenzyl Ethers by an Electronically Tuned Nitroxyl Radical Catalyst, Safety of 1-(Chloromethyl)-4-(trifluoromethyl)benzene, the publication is Organic Letters (2020), 22(14), 5486-5490, database is CAplus and MEDLINE.

The oxidation of p-methoxy benzyl (PMB) ethers e.g., 1-methoxy-4-[(3-phenylpropoxy)methyl]benzene was achieved using nitroxyl radical catalyst I, which contains electron-withdrawing ester groups adjacent to the nitroxyl group. The oxidative deprotection of the PMB moieties on the hydroxy groups was observed upon treatment of I with 1 equiv of the co-oxidant Ph iodonium bis(trifluoroacetate) (PIFA). The corresponding carbonyl compounds e.g., 3-phenylpropanal were obtained by treating the PMB-protected alcs., e.g., 3-phenylpropan-1-ol, with I and an excess of PIFA.

Hamdy, Rania published the artcileDesign and synthesis of new drugs inhibitors of Candida albicans hyphae and biofilm formation by upregulating the expression of TUP1 transcription repressor gene, Application of 1-(Chloromethyl)-4-(trifluoromethyl)benzene, the publication is European Journal of Pharmaceutical Sciences (2020), 105327, database is CAplus and MEDLINE.

Here, new compounds were designed to selectively inhibit C. albicans hyphae formation without affecting human cells to afford sufficient safety. The newly designed 5-[3-substitued-4-(4-substituedbenzyloxy)-benzylidene]-2-thioxo-thiazolidin-4-one derivatives, named SR, I (R¹ = 4-Me, 4-CF₃, 3-CF₃; R² = OMe, Cl, Br) showed very specific and effective inhibition activity against C. albicans hyphae formation. SR compounds caused hyphae inhibition activity at concentrations 10-40 fold lower than the concentration required to inhibit Candida yeast and bacterial growths. The anti-hyphae inhibition activities of SR compounds were via activation of the hyphae transcription repressor gene, TUP1. Correlation studies between the expression of TUP1 gene and the activity of SR compounds confirmed that the anti-C. albicans activities of SR compounds were via inhibition of hyphae formation. The newly designed SR compounds showed 10-40% haemolytic activity on human erythrocytes when compared to 100% haemolysis by 0.1% triton employed as pos. control. Furthermore, theor. prediction of absorption, distribution, metabolism, excretion, and toxicity (ADMET) of SR compounds confirmed their safety, efficient metabolism and possible oral bioavailability. With the minimal toxicity and significant activity of the newly-designed SR compounds, a future optimization of pharmaceutical formulation may develop a promising inhibitor of hyphal formation not only for C. albicans but also for other TUP1-dependent dimorphic fungal infections.

Yang, Peng-Fei published the artcileRegio- and Enantioselective Hydroalkylations of Unactivated Olefins Enabled by Nickel Catalysis: Reaction Development and Mechanistic Insights, Name: 1-(Chloromethyl)-4-(trifluoromethyl)benzene, the publication is ACS Catalysis (2022), 12(10), 5795-5805, database is CAplus.

Direct construction of fully alkyl-substituted tertiary chiral centers remote to activating groups is highly challenging and desirable. Herein, a Ni-catalyzed enantioselective hydroalkylation of unactivated alkenes with unactivated alkyl halides at room temperature is reported, providing a general and practical access to fully alkyl-substituted tertiary stereogenic carbon centers not adjacent to activating groups. This reaction undergoes regio- and stereoselective hydrometalation of unactivated alkenes with a nontrivial Markovnikov selectivity, followed by cross-coupling with unactivated alkyl electrophiles to access trialkyl tertiary saturated stereogenic centers not adjacent to activating groups. The mild and robust conditions enable the use of terminal and internal unactivated alkenes and unactivated primary and secondary alkyl, benzyl and propargyl halides to construct diverse trialkyl tertiary stereogenic carbon centers with broad functional group tolerance. Moreover, exptl. investigations support the reaction undergoing irreversible and stereoselective hydrometalation of alkenes. D. functional theory calculations provide further insights into the reaction mechanism, suggesting a stereoselective migration insertion of alkenes with Ni(II)-H species. Finally, the origin of the regio- and enantioselectivities was also investigated.

A novel and practical route to coumarin derivatives was developed via the heterogeneous Pd-catalyzed carbonylative reaction and subsequent intramol. condensation process starting from com. easily available benzyl chlorides and salicylic aldehydes. Reactions were performed in the existence of 2 mol% of an SBA-15-immobilized bidentate phosphine palladium complex [SBA-15-P,P-PdCl2] in dioxane at 110°C with Et₃N as base under 10 bar of CO to afford a wide range of coumarin derivatives mostly with good to high yields. Importantly, this new heterogenized palladium complex was easy to recover via filtration of the reaction mixture, and was recyclable up to 8 times without apparent drop in its catalytic performance.

Yang, Guangqian published the artcileStudy of the in vivo antiviral activity against TMV treated with novel 1-(t-butyl)-5-amino-4-pyrazole derivatives containing a 1,3,4-oxadiazole sulfide moiety, Quality Control of 939-99-1, the publication is Pesticide Biochemistry and Physiology (2021), 104740, database is CAplus and MEDLINE.

A series of new 1-tert-butyl-5-amino-4-pyrazole bioxadiazole sulfide derivatives containing a 1,3,4-oxadiazole moiety were designed and synthesized. The bioactivity results showed that some title compounds exhibited excellent protective activity against TMV and certain insecticidal activity. Among the tested compounds, the EC₅₀ values of 5d, 5j, 5k and 5l were 165.8, 163.2, 159.7 and 193.1 mg/L, resp., which are better than the EC₅₀ value of ningnanmycin (271.3 mg/L). The chlorophyll contents and the defense enzyme activities of the tobacco leaves after treatment with 5j were significantly increased, which indicated that this series of title compounds may induce the systemic acquired resistance of host to defend against diseases. Further in vivo protective activity research on 5j using TMV with a GFP gene tag found that it can effectively inhibit the spread of TMV in inoculated tobacco. A morphol. study with TEM revealed that title compound 5h can cause a distinct break of the rod-shaped TMV. Moreover, the insecticidal activity revealed that the fatality rates of 5a, 5b and 5m against aphidoidea were 85%, 83% and 87%, resp., which indicated that the title compounds can effectively block the common carrier of plant viruses, thereby effectively reducing the TMV infection risk of tobacco. This series of synergistic effects provide key information for the research and development of antiviral agents.
