We report the synthesis and biological activity of a series of analogues of the vasopressin antagonists [Pmp1,D-Tyr(Et)2,Val4]arginine-vasopressin (1) and [Pmp1,D-Tyr(Et)2,Val4,desGly9]arginine-vasopressin (2), where part or all of the tripeptide tail has been replaced by a simple alkyldiamine [NH(CH2)nNH2] or (aminoalkyl)guanidine [NH(CH2)nNHC(= NH)NH2] in(More)
Certain 6-halo-1-phenyl-2,3,4,5-tetrahydro-1H-3-benzazepines were found to be potent D-1 dopamine agonists. The 1-(4-hydroxyphenyl) analogues did not have central nervous system activity because their high polarity inhibited entry into the brain. However, these compounds were potent renal vasodilators. Fenoldopam, the 6-chloro analogue, is an especially(More)
Our molecular modeling studies suggested that the conformational effects of the "cystine-line" residue Pmp1-Cys6 on the cyclohexapeptide ring of the vasopressin antagonist [Pmp1,D-Phe2,Val4]AVP might be mimicked by substitution of D-aminoadipic acid at position 6 and cyclization of its side-chain carboxyl to the alpha-amine of residue 2. The peptide was(More)
We read with interest the comments offered by Drs. Hughes and Bradley (1) on our systematic review (2). Four single nucleotide polymorphisms (SNPs), rs9332739 and rs547154 in the complement component 2 gene (C2) and rs4151667 and rs641153 in the complement factor B gene (CFB), were pooled. Hughes and Bradley point out that we omitted the most common(More)
In a search for inhibitors of epinephrine biosynthesis as potential therapeutic agents, a series of 13 ring-chlorinated 1,2,3,4-tetrahydroisoquinolines was prepared. These compounds were tested initially for their ability to inhibit rabbit adrenal phenylethanolamine N-methyltransferase (PNMT) in vitro. Enzyme-inhibitor dissociation constants, determined for(More)
The oral-facial-digital syndromes (OFDS) are a heterogeneous group. Recently, Gurrieri et al. [1992: Am J Med Genet 42:789-792] described a new OFDS characterised by typical oral, facial and digital abnormalities but distinguishable from previously reported OFDS by the presence of retinochoroidal lacunae of an apparently colobomatous origin. Toriello [1993:(More)
