The structure-activity studies leading to the potent and clinically efficacious HIV protease inhibitor ritonavir are described. Beginning with the moderately potent and orally bioavailable inhibitor A-80987, systematic investigation of peripheral (P3 and P2') heterocyclic groups designed to decrease the rate of hepatic metabolism provided analogues with improved pharmacokinetic properties after oral dosing in rats. Replacement of pyridyl groups with thiazoles provided increased chemical stability toward oxidation while maintaining sufficient aqueous solubility for oral absorption. Optimization of hydrophobic interactions with the HIV protease active site produced ritonavir, with excellent in vitro potency (EC50 = 0.02 μM) and high and sustained plasma concentrations after oral administration in four species. Details of the discovery and preclinical development of ritonavir are described.
Structure-activity studies of 6-substituted decahydroisoquinoline-3- carboxylic acid AMPA receptor antagonists. 2. Effects of distal acid bioisosteric substitution, absolute stereochemical preferences, and in vivo activity

, p. 2232 - 2244 (2007/10/03)
We have explored the excitatory amino acid antagonist activity in a series of decahydroisoquinoline-3-carboxyic acids, and within this series found the potent and selective AMPA antagonist (3SR,4aRS,6RS,8aRS)-6-(2-(1H-tetrazol- 5-yl)ethyl)decahydroisoquin

, p. 1336 - 1344 (2007/10/02)
Semisynthetic analogues of pseudomonic acid A have been prepared containing a heterocyclyl substituted oxazole. Derivatives in which the heterocycle was thiophene, furan, pyridine, or isoxazole showed good antibacterial potency and were further evaluated in vivo. Both pharmacokinetic parameters and oral activity against an experimental intraperitoneal sepsis were superior to results obtained from previously described pseudomonic acid A derivatives.
Condensation of muscimol or thiomuscimol with aminopyridazines yields GABA-A antagonists
Melikian,Schlewer,Chambon,Wermuth
, p. 4092 - 4097 (2007/10/02)
Ten analogs of muscimol and thiomuscimol in which the amino function was delocalized in an amidinic system were prepared by N2 alkylation of 6-aryl-3- aminopyridazines with (chloromethyl)isoxazole or (chloromethyl)isothiazole derivatives. These muscimol a
Process for the preparation of 3,5-disubstituted isoxazoles
-
, (2008/06/13)
A novel process for the preparation of 3-bromo- and 3-chloro-5-substituted isoxazoles is provided. Dibromo- or dichloro-formaldoxime is reacted with an excess of an 1-alkyne derivative of the formula where R is hydrogen, phenyl or 1-6 C alkyl optionally substituted by halogen, OH, OR', CHO, COR', COOR', CONH2, CONR'R" or NHCOR' where, in turn, R' and R", which may be the same or different, are a 1-6 C alkyl or haloalkyl, in the presence of (i) at least an equimolecular amount, with respect to the dibromo- or dichloro-formaldoxime, of an alkaline base selected from the class consisting of sodium and potassium carbonate and bicarbonate and (ii) an inert solvent in which the 1-alkyne is soluble at room temperature.
