Synthetic Route of 3445-52-1, Chemistry is the science of change. But why do chemical reactions take place? Why do chemicals react with each other? The answer is in thermodynamics and kinetics.In a document type is Article, and a compound is mentioned, 3445-52-1, 5-Methylisoxazole-3-carboxamide, introducing its new discovery.

We previously reported the identification of (2S)-((2- benzoylphenyl)amino)-3-{4-[2-(5-methyl-2-phenyloxazol-4- yl)ethoxy]phenyl}propanoic acid (2) (PPARgamma pK(i) = 8.94, PPARgamma pEC50 = 9.47) as a potent and selective PPARgamma agonist. We now report the expanded structure-activity relationship around the phenyl alkyl ether moiety by pursuing both a classical medicinal chemistry approach and a solid-phase chemistry approach for analogue synthesis. The solution-phase strategy focused on evaluating the effects of oxazole and phenyl ring replacements of the 2-(5-methyl-2-phenyloxazol-4-yl)ethyl side chain of 2 with several replacements providing potent and selective PPARgamma agonists with improved aqueous solubility. Specifically, replacement of the phenyl ring of the phenyloxazole moiety with a 4-pyridyl group to give 2(S)-((2- benzoylphenyl)amino)-3-{4-[2-(5-methyl-2-pyridin-4-yloxazol-4- yl)ethoxy]phenyl}propionic acid (16) (PPARgamma pK(i) = 8.85, PPARgamma pEC50 = 8.74) or a 4-methylpiperazine to give 2(S)-((2-benzoylphenyl)amino)-3-(4- {2-[5-methyl-2-(4-methylpiperazin-1-yl)thiazol-4-yl]ethoxy}phenyl)propionic acid (24) (PPARgamma pK(i) = 8.66, PPARgamma pEC50 = 8.89) provided two potent and selective PPARgamma agonists with increased solubility in pH 7.4 phosphate buffer and simulated gastric fluid as compared to 2. The second strategy took advantage of the speed and ease of parallel solid-phase analogue synthesis to generate a more diverse set of phenyl alkyl ethers which led to the identification of a number of novel, high-affinity PPARgamma ligands (PPARgamma pK(i)’s 6.98-8.03). The combined structure-activity data derived from the two strategies provide valuable insight on the requirements for PPARgamma binding, functional activity, selectivity, and aqueous solubility.

One of the major reasons for studying chemical kinetics is to use measurements of the macroscopic properties of a system, name: 5-Methylisoxazole-3-carboxamide, such as the rate of change in the concentration of reactants or products with time.In a article, mentioned the application of 3445-52-1, Name is 5-Methylisoxazole-3-carboxamide, molecular formula is C5H6N2O2

The mineralocorticoid receptor (MR) is a nuclear hormone receptor involved in the regulation of body fluid and electrolyte homeostasis. In this study we explore selectivity triggers for a series of nonsteroidal MR antagonists to improve selectivity over other members of the oxosteroid receptor family. A biaryl sulfonamide compound was identified in a high-throughput screening (HTS) campaign. The compound bound to MR with pKi=6.6, but displayed poor selectivity over the glucocorticoid receptor (GR) and the progesterone receptor (PR). Following X-ray crystallography of MR in complex with the HTS hit, a compound library was designed that explored an induced-fit hypothesis that required movement of the Met852 side chain. An improvement in MR selectivity of 11- to 79-fold over PR and 23- to 234-fold over GR was obtained. Given the U-shaped binding conformation, macrocyclizations were explored, yielding a macrocycle that bound to MR with pKi=7.3. Two protein?ligand X-ray structures were determined, confirming the hypothesized binding mode for the designed compounds.

Palladium(II)-Catalyzed Sp3/Sp2 gamma- and delta-C-H Functionalization of Aryl Amines using 5-Methylisoxazole-3-Carboxamide as Directing Group

A dual objective-based study comprising exploration of 5-methylisoxazole-3-carboxamide (MICA) as a directing group (DG) for the Pd(II)-catalyzed sp3/sp2 gamma- and delta-C?H activation/functionalization of aryl amines and assembling of various MICA motifs are reported. The Pd(II)-catalyzed MICA-aided gamma-C(sp3)-H arylation/acetoxylation of ortho-toluidines gave various 2-aminodiphenylmethanes and 2-aminobenzyl acetates, respectively. The Pd(II)-catalyzed MICA-aided gamma-C(sp2)-H arylation/acetoxylation of benzylamines gave the corresponding arylated/acetoxylated products. Furthermore, the Pd(II)-catalyzed MICA-aided delta-C(sp2)-H amidation/alkenylation of phenethylamines were also explored. Representative control reactions were done to assess the relative effectiveness of MICA for the gamma-C(sp3)-H arylation and MICA is a removable DG. Apart from the usage of MICA as a DG for the sp2/sp3 C?H functionalization of aryl amines, indirectly this process has led to the construction of a library of MICA motifs. This is an added advantage to note as the MICA-based motifs are valuable small molecules in medicinal chemistry.
