Paragraph 0048-0122; 0226-0230; 0271-0272, (2020/05/01)
The invention discloses a green synthesis method of aromatic acid. Nickel-catalyzed carbonyl insertion is carried out on aryl iodine in the presence of formate, acid anhydride, a phosphine ligand andan organic solvent by using a nickel catalyst to obtain the aromatic acid. Efficient catalytic conversion is realized by utilizing the cheap nickel catalyst, the reaction conditions are mild, and theoperation is simple.

A protocol for the Ni-catalyzed carboxylation of aryl iodides with formate has been developed with good functional group compatibility for the synthesis of a variety of aromatic carboxylic acids under mild conditions. The reaction tolerates other functionalities for cross-coupling, such as aryl bromide, aryl chloride, aryl tosylate, and aryl pinacol boronate. The reaction proceeds through a carbonylation process with in situ generated carbon monoxide in the presence of a catalytic amount of acetic anhydride and lithium formate, avoiding the use of gaseous CO. The strategy of CO recycling in catalytic amounts is critical for the success of the reaction.

HSP90 is ubiquitously overexpressed in a broad spectrum of human cancers and has been recognized as an attractive target for cancer treatment. Here, we described the fragment screening, synthesis and structure-activity relationship studies of small molecule inhibitors with 4,5-diarylisoxazole scaffold targeting HSP90. Among them, the compound N-(3-(2,4-dihydroxy-5-isopropylphenyl)-4-(4-((4-morpholinopiperidin-1-yl)methyl)phenyl)isoxazol-5-yl)cyclopropanecarboxamide (108) showed high affinity for binding to HSP90 (FP binding assay, IC50 Combining double low line 0.030 μM) and inhibited the proliferation of various human cancer cell lines with averaging GI50 about 88 nM. Compound 108 exhibited its functional inhibition of HSP90 by depleting key signaling pathways and concomitantly elevating of HSP70 and HSP27 in U-87MG cells. Further in vivo studies showed that compound 108 strongly suppressed the tumor growth of human glioblastoma xenograft model U-87MG with T/C Combining double low line 18.35% at 50 mg/kg q3w/2.5w. Moreover, compound 108 also exhibited good pharmacokinetic properties. Together, our study implicates that compound 108 is a promising candidate of HSP90 inhibitor and is currently advanced to preclinical study.
