Weber, Philip; Rank, Christian K.; Yalcinkaya, Enis; Dyga, Marco; van Lingen, Tim; Schmid, Rochus; Patureau, Frederic W.; Goossen, Lukas J. published the article 《Rhodium-catalyzed ortho-Arylation of (Hetero)aromatic Acids》. Keywords: carboxylate heteroaryl preparation; heteroaryl aryl carboxylic acid preparation regioselective methyl iodide esterification; bromide aryl heteroaryl carboxylic acid arylation.They researched the compound: 6-Methylnicotinic acid( cas:3222-47-7 ).Recommanded Product: 3222-47-7. Aromatic heterocyclic compounds can be divided into two categories: single heterocyclic and fused heterocyclic. In addition, there is a lot of other information about this compound (cas:3222-47-7) here.

Rhodium acetate effectively promotes the carboxylate-directed ortho-arylation of (hetero)aromatic carboxylic acids ArCOOH (Ar = 2-methylphenyl, 4-methoxythiophen-3-yl, 2-fluoropyridin-3-yl, etc.) with aryl bromides Ar1Br (Ar1 = 4-methylphenyl, 2-naphthyl, 2-methylpyridin-6-yl, etc.) yielded functionalized hetero/aryl carboxylic acids, e.g., I (X = H, Me) and its Me carboxylates. The main advantage of this phosphine-free, redox-neutral method arises from its efficiency in assembling biol. meaningful electron-rich arylpyridines, which are problematic substrates in known C-H arylations using Pd, Ru, and Ir catalysts.

The reaction of an aromatic heterocycle with a proton is called a protonation. One of articles about this theory is 《5-(p-Aminobenzenesulfonamido)thiazole》. Authors are Arnold, M. H. M.; Scaife, C. W..The article about the compound:5-Aminothiazole-2-carbonitrilecas:860182-74-7,SMILESS:N#CC1=NC=C(N)S1).Name: 5-Aminothiazole-2-carbonitrile. Through the article, more information about this compound (cas:860182-74-7) is conveyed.

5-Amino-2-thiazolethiocarboxamide (I) (chrysean of Wallach, Ber. 7, 902(1874)), m. 204° (decomposition), results in 25-g. yield by passing H2S (20-30 l./hr.) into saturated aqueous NaCN and a little NH4OH for 3-4 hrs.; acidification of the filtrate gives 30-40% (of the NaCN) of a reddish brown precipitate which decomposes on heating with H2O to give H2S and a black alkali-soluble tar. Many other methods were tried with yields not over 15-20%. I (10 g.) and 23.9 g. Pb(OAc)2 in 70 ml. H2O, refluxed 3 hrs., give 5-amino-2-thiazolecarbonitrile (II), m. 103° (Hellsing, Ber. 32, 1497(1899)). If the filtrate containing II is treated with CaCO3 in slight excess above that required to neutralize the AcOH and the mixture is refluxed 2 hrs., there results a good yield of 5-amino-2-thiazolecarboxamide, decomposes 156°. Hydrolysis of II with dilute HCl gives a small yield of 2-amino-2-thiazolecarboxylic acid, decomposes 185°; this could not be decarboxylated to 5-aminothiazole. II and BzH in EtOH give the 5-benzylideneamino compound, light yellow, m. 141°; this and the benzylidene derivative of I are too easily hydrolyzed for this method of protecting the NH2 group to be of any use. Attempts to diazotize I and II in the normal way gave highly colored tars, which appeared to be formed by intermol. condensation; II is diazotized by gradual addition of the solution to excess of HCl and NaNO2 at 0°; I has been diazotized by adding its solution in C5H5N to excess of NOCl in C6H6. I and p-O2NC6H4SO2Cl in C5H5N give the 5-(p-nitrophenylsulfonamido) compound, m. 185° (decomposition); the same derivative of II m. 148°. p-AcNHC6H4SO2Cl and I in C5H5N give the 5-(p-acetamidophenylsulfonamido) compound (III), m., 253-5° (decomposition); shaking with PbCO3 and refluxing the filtrate for 3 hrs. give a moderately good yield of 5-sulfanilamidothiazole (IV), m. 185° (decomposition). III is completely inactive against streptococcal infections and IV, although active, has no advantage over established sulfonamide drugs.

Heterocyclic compounds can be divided into two categories: alicyclic heterocycles and aromatic heterocycles. Compounds whose heterocycles in the molecular skeleton cannot reflect aromaticity are called alicyclic heterocyclic compounds. Compound: 86404-63-9, is researched, Molecular C10H7F2N3O, about Structure-based rational design, synthesis and antifungal activity of oxime-containing azole derivatives, the main research direction is triazolylpropanol piperidinone oxime ether containing derivative preparation antifungal activity; mol docking CACYP51 triazolylpropanol piperidinone oxime ether containing derivative.Recommanded Product: 1-(2,4-Difluorophenyl)-2-(1H-1,2,4-triazol-1-yl)ethanone.

In an attempt to find novel azole antifungal agents with improved activity and broader spectrum, computer modeling was used to design a series of new azoles with piperidin-4-one O-substituted oxime side chains. Mol. docking studies revealed that they formed hydrophobic and hydrogen-bonding interactions with lanosterol 14α-demethylase of Candida albicans (CACYP51). In vitro antifungal assay indicates that most of the synthesized compounds showed good activity against tested fungal pathogens. In comparison with fluconazole, itraconazole and voriconazole, several compounds (such as I, R = H, 3-Cl, 2-F) show more potent antifungal activity and broader spectrum, suggesting that they are promising leads for the development of novel antifungal agents.

Compound: 6-Methylnicotinic acid, is researched, Molecular C7H7NO2, CAS is 3222-47-7, about Discovery of quinolone derivatives as antimycobacterial agents. Author is Liu, Kun-Lin; Teng, Fei; Xiong, Lu; Li, Xiao; Gao, Chao; Yu, Luo-Ting.

In this report, a compound library was screened and identified compound I with antituberculosis activity and a minimal inhibitory concentration (MIC) against M. tuberculosis of 20μg mL-1. Structure optimization and the structure-activity relationship of 1 as the lead compound enabled the design and synthesis of a series of quinolone derivatives, e.g, II. These compounds were evaluated in vitro for anti-tubercular activity against the M. tuberculosis H37Rv strain. Among them, compounds III [n = 1; R = 3′,5′-dimethoxy-[1,1′-biphenyl], 4-(trifluoromethyl)phenyl, 6-(trifluoromethyl)pyridin-3-yl (IV)] exhibited MIC values in the range of 1.2-3μg mL-1 and showed excellent activity against the tested MDR-TB strain (MIC: 3, 2.9 and 0.9μg mL-1, resp.). All three compounds III were non-toxic toward A549 and Vero cells (>100 and >50μg mL-1, resp.). In addition, an antibacterial spectrum test carried out using compound (IV) showed that this compound specifically inhibits M. tuberculosis. These can serve as a new starting point for the development of anti-TB agents with therapeutic potential.

The preparation of ester heterocycles mostly uses heteroatoms as nucleophilic sites, which are achieved by intramolecular substitution or addition reactions. Compound: 5-(Chloromethyl)nicotinonitrile( cas:562074-59-3 ) is researched.Recommanded Product: 562074-59-3.Kawashita, Seiji; Aoyagi, Koichi; Yamanaka, Hiroshi; Hantani, Rie; Naruoka, Shiori; Tanimoto, Atsuo; Hori, Yuji; Toyonaga, Yukiyo; Fukushima, Kyoko; Miyazaki, Susumu; Hantani, Yoshiji published the article 《Symmetry-based ligand design and evaluation of small molecule inhibitors of programmed cell death-1/programmed death-ligand 1 interaction》 about this compound( cas:562074-59-3 ) in Bioorganic & Medicinal Chemistry Letters. Keywords: immune checkpoint inhibitor surface plasmon resonance PD1 PDL1; Drug design; Immune checkpoint inhibitor; PD-1; PD-L1; Small-molecules; Surface plasmon resonance. Let’s learn more about this compound (cas:562074-59-3).

The development of small mol. inhibitors of PD-1/PD-L1 is eagerly anticipated for treatment of cancer. We focused on the symmetry of the ternary complex structure of reported small mol. ligands and hPD-L1 homodimers, and designed partially- or fully-sym. compounds for more potent inhibitors. The design of the new compounds was guided by our hypothesis that the designed sym. compound would induce a flip of sidechain of ATyr56 protein residue to form a new cavity. The designed compound 4 exhibited substantially increased binding affinity to hPD-L1, as well as PD-1/PD-L1 inhibitory activity in physiol. conditions. Compound 4 also showed a dose-dependent increase in IFN-γ secretion levels in a mixed lymphocyte reaction assay. These results not only indicate the feasibility of targeting the PD-1/PD-L1 pathway with small mols., but illustrate the applicability of the symmetry-based ligand design as an attractive methodol. for targeting protein-protein interaction stabilizers.

This literature about this compound(562074-59-3)Recommanded Product: 562074-59-3has given us a lot of inspiration, and I hope that the research on this compound(5-(Chloromethyl)nicotinonitrile) can be further advanced. Maybe we can get more compounds in a similar way.
