We recently reported the development of the BDNF mimetic peptide cyclo-[dPAKKR] 1 which promotes the survival of cultured sensory neurons via a trkB independent mechanism [Fletcher, J. M.; Morton, C. M.; Zwar, R. A.; Murray, S. S.; O’Leary, P. D.; Hughes, R. A. J. Biol. Chem. 2008, 283, 33375]. In the present study we prepared a series of hydrophobically-modified analogues of 1 with an eye to improving
我们最近报道了BDNF模拟肽环[dPAKKR] 1的开发,该环通过trkB独立机制促进培养的感觉神经元的存活[Fletcher,JM; CM,莫顿;Zwar,RA; SS Murray;O'Leary,PD;休斯,RAJ。化学 2008年,283,33375]。在本研究中,我们着眼于改善其药代动力学特性,制备了一系列疏水改性的1的类似物。第二代化合物的精选成员显示出改善的生物活性,在血浆中的稳定性以及跨模型生物膜的能力。
