Synthesis and in vitro evaluation of derivatives of the β1-adrenergic receptor antagonist HX-CH 44
摘要:
Isopropyl- and fluoroisopropyl-amino derivatives of the beta(1)-adrenergic receptor antagonist 2-[4-[3-(tert-butyl-amino)-2-hydroxypropoxy]phenyl]-3-methyl-6-methoxy-4(3H)-quinazolinone ((+/-) HX-CH 44) were synthesized, including a concise and efficient preparation of the core, 2-(4-hydroxyphenyl)-6-methoxy-3-methylquinazolin-4(3H)-one. In vitro binding assays showed that the fluorinated analog was selective towards beta(1)-adrenergic receptors over beta(2)-adrenergic and 5-HT1A receptors. An X-ray crystallographic characterization of the fluorinated analog is also reported. (C) 2011 Elsevier Ltd. All rights reserved.

An efficient and genral method has been developed for fluorine-18 labeling of beta-blockers that possess the propanolamine moiety. A new synthetically versatile intermediate, 3-(1-(benzyloxy)propan-2-yl)-2-oxoox-azolidin-5-yl)methyl 4-methylbenzenesulfonate (13), was prepared and can be conjugated to any phenoxy core. To demonstrate the synthetic methodology, fluorinated derivatives of toliprolol were prepared, namely, [(18)F]-(2S and 2R)-]-(1-fluoropropan-2-ylamino)-3-(m-tolyloxy)propan-2-ol ((2S and 2R)-[(18)F]1). The radiosyntheses were accomplished in < 1 h, with 20-24% (uncorrected for decay, n = 7) radiochemical yields, > 96% radiochemical and > 99% enantiomeric purities, with specific activities of 0.9-1.1 Ci/mu mol(EOS). Ex vivo biodistribution studies with the radiotracers demonstrated excessively rapid washout that May limit their use for cerebral PET imaging.
