Ethyl pyrazole-4-carboxylate is a low yield, transition metal salt that is used in the synthesis of pyrazoles. It can be synthesized by the reaction of sodium ethoxide with ethyl chloroformate and a Grignard reagent. Sodium ethoxide is added to a suspension of sodium chloride and dried ethyl chloroformate, followed by addition of magnesium turnings. The mixture is refluxed for one hour, cooled, and filtered to give crystals. Ethyl pyrazole-4-carboxylate is used in the preparation of ethyl esters from aliphatic alcohols by reacting with boron trichloride or phosphorus pentachloride. It participates in certain chemical reactions as a byproduct and can damage equipment during chemical reactions. The yield of this compound can be increased by using an excess amount of Grignard reagent or adding hexamethylenetetramine to the reaction mixture, 37622-90-5.

Histone deacetylase 6 (HDAC6) is a promising therapeutic target for the treatment of neurodegenerative disorders. SW-100 (1a), a phenylhydroxamate-based HDAC6 inhibitor (HDAC6i) bearing a tetrahydroquinoline (THQ) capping group, is a highly potent and selective HDAC6i that was shown to be effective in mouse models of Fragile X syndrome and Charcot-Marie-Tooth disease type 2A (CMT2A). In this study, we report the discovery of a new THQ-capped HDAC6i, termed SW-101 (1s), that possesses excellent HDAC6 potency and selectivity, together with markedly improved metabolic stability and druglike properties compared to SW-100 (1a). X-ray crystallog. data reveal the mol. basis of HDAC6 inhibition by SW-101 (1s). Importantly, we demonstrate that SW-101 (1s) treatment elevates the impaired level of acetylated α-tubulin in the distal sciatic nerve, counteracts progressive motor dysfunction, and ameliorates neuropathic symptoms in a CMT2A mouse model bearing mutant MFN2. Taken together, these results bode well for the further development of SW-101 (1s) as a disease-modifying HDAC6i.

Part 9: Multiplex inhibitors suppressing compensatory activations of RTKs》, the research content is summarized as follows. Aberrant angiogenesis is a hallmark of various diseases including cancers. VEGFR-2 inhibitors have been utilized as anti-angiogenic agents for several years. However, compensatory activation of various receptor tyrosine kinases (RTK) could induce the occurrence of resistance. The authors previously reported a series of multi-target inhibitors of VEGFR-2, Tie-2, and EphB4 as anti-angiogenic agents. These inhibitors might be a promising strategy to overcome the resistance induced by compensatory activation. To expand the structural diversity of these multiple RTK inhibitors, the authors described herein the design, synthesis, and evaluation of a novel class of triplet VEGFR-2/TIE-2/EphB4 inhibitors. The biol. evaluation indicated that five compounds exhibited simultaneous VEGFR-2/Tie-2/EphB4 inhibitory activities with IC₅₀ values less than 50 nM.
