Histone deacetylase 6 (HDAC6) function and dysregulation have been implicated in the etiol. of certain cancers and more recently in central nervous system (CNS) disorders including Rett syndrome, Alzheimer’s and Parkinson’s diseases, and major depressive disorder. HDAC6-selective inhibitors have therapeutic potential, but in the CNS drug space the development of highly brain penetrant HDAC inhibitors has been a persistent challenge. Moreover, no tool exists to directly characterize HDAC6 and its related biol. in the living human brain. Here, we report a highly brain penetrant HDAC6 inhibitor, Bavarostat, that exhibits excellent HDAC6 selectivity (>80-fold over all other Zn-containing HDAC paralogues), modulates tubulin acetylation selectively over histone acetylation, and has excellent brain penetrance. We further demonstrate that Bavarostat can be radiolabeled with 18F by deoxyfluorination through in situ formation of a ruthenium π-complex of the corresponding phenol precursor: the only method currently suitable for synthesis of [18F]Bavarostat. Finally, by using [18F]Bavarostat in a series of rodent and nonhuman primate imaging experiments, we demonstrate its utility for mapping HDAC6 in the living brain, which sets the stage for first-in-human neurochem. imaging of this important target.

The Best Chemistry compound: 97739-46-3

After consulting a lot of data, we found that this compound(97739-46-3)Application of 97739-46-3 can be used in many types of reactions. And in most cases, this compound has more advantages.

The reaction of an aromatic heterocycle with a proton is called a protonation. One of articles about this theory is 《Aromatic silicon systems. II. The silacyclopentadienide anion》. Authors are Benkeser, Robert A.; Grossman, Richard F.; Stanton, Garth M..The article about the compound:1,3,5,7-Tetramethyl-6-phenyl-2,4,8-trioxa-6-phosphaadamantanecas:97739-46-3,SMILESS:CC1(C2)OC(C3)(C)OC2(C)OC3(C)P1C4=CC=CC=C4).Application of 97739-46-3. Through the article, more information about this compound (cas:97739-46-3) is conveyed.

cf. ibid. 4723. Silacyclopentadiene (I) has been found to react directly with K forming H and II. Comparison of the nuclear magnetic resonance spectra of I and II provides graphic evidence that it is the silanic hydrogens which are replaced by the metal in this reaction. Significantly, divinylsilane (the open chain analog of I) does not react with K at any appreciable rate under comparable conditions. This suggests that resonance stabilization of the silacyclopentadienide anion is providing a driving force for this reaction. II reacts with bromobenzene forming a mixture of 1-phenyl- and 1,1-diphenylsilacydopentadiene. The structure of the latter two compounds was established by reducing them catalytically to phenylated silacydopentanes which, in turn, could be prepared by unequivocal routes. II is colored in tetrahydrofuran solutions and possesses a spectrum which is quite similar to K in the visible region. All of the foregoing observations point to some measure of resonance stabilization in the silacyclopentadienide ring system, suggesting that the “”Hueckel rule”” will enjoy some success in predicting aromatic character for certain silicon ring systems
