The three-dimensional configuration of the ester heterocycle is basically the same as that of the carbocycle. Compound: 6-Methylnicotinic acid(SMILESS: O=C(O)C1=CN=C(C)C=C1,cas:3222-47-7) is researched.Application of 2923-28-6. The article 《Generating Multibillion Chemical Space of Readily Accessible Screening Compounds》 in relation to this compound, is published in iScience. Let’s take a look at the latest research on this compound (cas:3222-47-7).

An approach to the generation of ultra-large chem. libraries of readily accessible (‘REAL’) compounds is described. The strategy is based on the use of two- or three-step three-component reaction sequences and available starting materials with pre-validated chem. reactivity. After the preliminary parallel experiments, the methods with at least ~80% synthesis success rate (such as acylation – deprotection – acylation of monoprotected diamines e.g., 1-boc-amino-butyl-3-amine or amide formation e.g., N-(9-acetyl-9-azabicyclo[3.3.1]nonan-3-yl)-1H-indazole-3-carboxamide – click reaction with functionalized azides e.g., 3-(azidomethyl)-piperidine) can be selected and used to generate the target chem. space. It is shown that by using only on the two aforementioned reaction sequences, a nearly 29-billion compound library is easily obtained. According to the predicted physico-chem. descriptor values, the generated chem. space contains large fractions of both drug-like and ‘beyond rule-of-five’ members, whereas the strictest lead-likeness criteria (the so-called Churcher’s rules) are met by the lesser part, which still exceeds 22 million.

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:86404-63-9) here.

In response to the urgent need for novel antifungal agents with improved activity and broader spectrum, computer modeling was used for rational design of novel antifungal azoles. On the basis of the active site of lanosterol 14α-demethylase from Candida albicans (CACYP51), a series of new azoles with substituted-phenoxypropyl piperazine side chains were rationally designed and synthesized. In vitro antifungal activity assay indicates that the new azoles show good activity against most of the tested pathogenic fungi. Interestingly, the designed compounds are also active against an azole-resistant clin. strain. Compared to fluconazole and itraconazole, several compounds (such as I) show higher antifungal activity and a broader spectrum, which are promising leads for the development of novel antifungal agents.

Epoxy compounds usually have stronger nucleophilic ability, because the alkyl group on the oxygen atom makes the bond angle smaller, which makes the lone pair of electrons react more dissimilarly with the electron-deficient system. Compound: 6-Methylnicotinic acid, is researched, Molecular C7H7NO2, CAS is 3222-47-7, about The small molecule GAT1508 activates brain-specific GIRK1/2 channel heteromers and facilitates conditioned fear extinction in rodents.Related Products of 3222-47-7.

G-protein- gated inwardly-rectifying K+ (GIRK) channels are targets of Gi/o-protein-signaling systems that inhibit cell excitability. GIRK channels exist as homotetramers (GIRK2 and GIRK4) or heterotetramers with nonfunctional homomeric subunits (GIRK1 and GIRK3). Although they have been implicated in multiple conditions, the lack of selective GIRK drugs that discriminate among the different GIRK channel subtypes has hampered investigations into their precise physiol. relevance and therapeutic potential. Here, we report on a highly-specific, potent, and efficacious activator of brain GIRK1/2 channels. Using a chem. screen and electrophysiol. assays, we found that this activator, the bromothiophene-substituted small mol. GAT1508, is specific for brain-expressed GIRK1/2 channels rather than for cardiac GIRK1/4 channels. Computational models predicted a GAT1508- binding site validated by exptl. mutagenesis experiments, providing insights into how urea-based compounds engage distant GIRK1 residues required for channel activation. Furthermore, we provide computational and exptl. evidence that GAT1508 is an allosteric modulator of channel-phosphatidylinositol 4,5-bisphosphate interactions. Through brain-slice electrophysiol., we show that subthreshold GAT1508 concentrations directly stimulate GIRK currents in the basolateral amygdala (BLA) and potentiate baclofen-induced currents. Of note, GAT1508 effectively extinguished conditioned fear in rodents and lacked cardiac and behavioral side effects, suggesting its potential for use in pharmacotherapy for post-traumatic stress disorder. In summary, our findings indicate that the small mol. GAT1508 has high specificity for brain GIRK1/2 channel subunits, directly or allosterically activates GIRK1/2 channels in the BLA, and facilitates fear extinction in a rodent model.
