Abstract

The synthesis and characterization of a system for the study of molecular recognition phenomena are described. The system involves a tetraurea molecule that is capable of assembly into various associated states through hydrogen bonding. In organic solvents, the dynamic transition between a low-ordered (aggregate) state and a highly ordered dimeric assembly can be induced by the introduction of smaller molecules of appropriate size and shape. These smaller molecules, such as benzene, adamantanes, and ferrocenes, act as guests that occupy the pseudospherical capsule formed by the dimeric host. Among various guests, those that best fill the cavity and offer chemical complementarity to the host are preferentially encapsulated.

Esters of 3-pyridylacetic acid that combine potent inhibition of 17 alpha-hydroxylase/C17,20-lyase (cytochrome P45017 alpha) with resistance to esterase hydrolysis.

Esters of 3- and 4-pyridylacetic acid have been prepared and tested for inhibitory activity toward the human testicular 17 alpha-hydroxylase/C17,20-lyase and human placental aromatase enzymes. The structural features required for optimal inhibition of the hydroxylase/lyase enzyme were a 3-pyridine ring, methyl substitution alpha to the carbonyl group, and a bulky alkoxycarbonyl substituent. The compounds with the greatest selectivity were isopinocampheyl 2-methyl-2-(3-pyridyl)propanoate, 9, 1-adamantyl 2-methyl-2-(3-pyridyl)propanoate, 12, and 2-methyl-2-adamantyl 2-methyl-2-(3-pyridyl)propanoate, 14, which, while inhibiting the aromatase activity with IC50 values of 30, 35, and 40 microM, respectively, exhibited IC50 values toward hydroxylase/lyase of between 13 and 90 nM. For comparison, ketoconazole gave an IC50 value of 15 microM against aromatase and values of 65 and 26 nM for inhibition of the hydroxylase and lyase activities, respectively. Some of the structural features required for enzyme inhibition also conferred resistance to esterase hydrolysis, in vitro using rat liver microsomes as a source of the esterase activity. Therefore these esters are lead compounds in the development of inhibitors of androgen biosynthesis for the treatment of hormone-dependent prostatic cancer.

Modification of receptor selectivity and functional activity in cholecystokinin peptoid ligands.

Hybrid analogs of the cholecystokinin A (CCK-A) receptor selective tetrapeptide agonist Boc-Trp-Lys(Tac)-Asp-MePhe-NH2 (1,A-71623) and the CCK-B receptor selective antagonists PD-135118 (2) and CI-988 (3) were prepared. Incorporation of the Lys(Tac) side chain into 2 produced a moderately potent antagonist of CCK-8 in the isolated guinea pig gallbladder (GPGB). Incorporation of the Lys(Tac) side chain into 3 produced the novel agonist analog 7 (EC50 = 28 nM in the GPGB) with excellent affinity for both human CCK-A (IC50 = 12 nM) and CCK-B (IC50 = 17 nM) receptors. Analog 7 was a full agonist (EC50 = 3.5 nM) for calcium mobilization on CHO-K1 cells expressing hCCK-A receptors but a partial agonist on CHO-K1 cells expressing hCCK-B receptors, eliciting a weak agonist response (EC50 = 2800 nM) and antagonizing CCK-8-induced calcium mobilization (KB = 20 nM). Despite this unusual in vitro profile, analog 7 was a potent anorectic agent in rats (ED50 = 30 nmol/kg) following intraperitoneal administration.

International guide to drugs for Parkinson's disease.

Pharmacotherapy of Parkinson's disease (PD) has become so effective that patients with PD can enjoy a nearly normal life, including travel for several years. The degree of international travel of patients with PD and in particular the recent increased coordination between health systems in the European community call for a detailed information on the different antiparkinsonian drugs available worldwide. To provide an overview for physicians and patients on the diversity of preparations available in the different countries, we compiled the most commonly used substances along with their size of dosage and formula in an international guide to drugs for PD.
