Background: Phosgene (carbonyl dichloride) gas is an indispensable chemical inter-mediate used in numerous industrial processes. There is no clear consensus as to its time- and inhaled-dose-dependent etiopathologies and associated preventive or therapeutic treatment strategies. Methods: Cardiopulmonary function was examined in rats exposed by inhalation to the alveolar irritant phosgene or to the airway irritant chlorine during and following exposure. Terminal measurements focused on hematology, protein extravasation in bronchoalveolar lavage (BAL), and increased lung weight. Noninvasive diagnostic and prognostic endpoints in exhaled breath (carbon dioxide and nitric oxide) were used to detect the clinically occult stage of pulmonary edema. Results: The first event observed in rats following high but sublethal acute exposure to phosgene was the stimulation of alveolar nociceptive vagal receptors. This afferent stimulation resulted in dramatic changes in cardiopulmonary functions, ventilation: perfusion imbalances, and progressive pulmonary edema and phospholipoproteinosis. Hematology revealed hemoconcentration to be an early marker of pulmonary edema and fibrin as a discriminating endpoint that was positive for the airway irritant chlorine and negative for the alveolar irritant phosgene. Conclusions: The application of each gas produced typical ALI/ARDS (acute lung injury/acute respiratory distress syndrome) characteristics. Phosgene-induced ALI showed evidence of persistent apnea periods, bradycardia, and shifts of vascular fluid from the peripheral to the pulmonary circulation. Carbon dioxide in expired gas was suggestive of increased ventilation dead space and appeared to be a harbinger of progressively developing lung edema. Treatment with the iNOS inhibitor aminoguanidine aerosol by inhalation reduced the severity of phosgene-induced ALI when applied at low dose-rates. Symptomatic treatment regimens were considered inferior to causal modes of treatment.

Inhibition of cyclin-dependent kinases (CDKs) has emerged as an attractive strategy for the development of novel oncology therapeutics. Herein is described the utilization of an in vivo screening approach with integrated efficacy and tolerability parameters to identify candidate CDK inhibitors with a suitable balance of activity and tolerability. This approach has resulted in the identification of SCH 727965, a potent and selective CDK inhibitor that is currently undergoing clinical evaluation.

To validate a proposed solid support synthesis strategy for the construction of 2,6,9-trisubstituted purine based CDK inhibitors, the N-9 THP protected 6-benzylthio-2-iodopurine 11 was reacted with piperidine-2-methanol to give 12. Alternatively, intermediate 11 was converted to the C-2 acetylenyl substituted purine 16 in five steps, involving N-9 alkylation (Mitsunobu reaction), a Pd(0)-CuI-catalyzed acetylene coupling, selective activation of the 6-sulfur substituent and its displacement by ArCH2NH2.

A synthetic route to a new class of privileged tri- and tetra-cyclic quinazolines containing a medium-sized ring is reported. An expedient synthetic route involving nucleophilic aromatic substitution, and sequential Niementowski and BOP-mediated ring closures afforded a collection of analogues. The scope of the reaction was explored in terms of cyclic and acyclic linkers, ring size and substitution pattern.

Several novel 2-aryl-1,3-oxazinane and 2-aryl-1,3-oxazolidine derivatives were synthesized from N-benzyl-2-piperidineethanols and N-benzyl-2- piperidinemethanols, respectively, by using electrooxidative methods in methanol. For these reactions, the yields of the corresponding cyclized compounds were significantly increased by using catalytic amounts of iodide ions. In contrast, 3-dialkylamino-1-phenylpropanols afforded the expected cyclic 6-phenyl-1,3-oxazinane derivatives using only a small excess of base. Georg Thieme Verlag Stuttgart · New York.

In the optimization of the ring-opening reaction of thiophene-1,1- dioxides, 3-bromo-2,5-dimethylthiophene-1,1-dioxide (1) and 2-(2- hydroxyethyl)piperidine (7) were chosen as model reagents. Solvent, temperature, molar ratio between amine and dioxide and the amount of solvent were variables included in the optimization. A central composite design was chosen for the investigation and a canonical analysis of the response surface was performed. When reacting 3-bromo-2- isopropyl-5- trideuteriomethylthiophene-1,1-dioxide (25) with 7 a primary kinetic isotope effect, diminished by internal return, was found for the initial proton abstractions as well as an intramolecular deuterium transfer in the tautomerization of 23.

Several imidazo and pyrimido[1,2-a]pyrimidinones of type 1 and 2 were synthesized through intramolecular cyclization of pyrimidines 9 or pyrimidinones 10 bearing a variety of beta and gamma-aminoalcohols at the 2-position. Ring closure of the pyrimidinones of type 10 under Mitsunobu conditions lead to mixtures of both bicyclic regioisomers 1 and 2. Treatment of pyrimidines of type 9 with H2SO4 provided an efficient and operationally simple one-pot hydrolysis-cyclization procedure for obtaining imidazo and pyrimido[1,2-a]pyrimidinones 1 in good yields as the sole regioisomeric bicyclic product.

(equation presented) The conjugate additions of beta- and gamma-chloroamines to acetylenic sulfones afford enamine sulfones, which then undergo intramolecular alkylation to produce the corresponding cyclic enamines. This provides a convenient route to substituted piperidines, indolizidines, quinolizidines, and pyrrolizidines. The enantioselective total synthesis of the alkaloid (-)-indolizidine 167B (also named gephyrotoxin 167B) was thus achieved by the cycloaddition of (S)-2-(2-chloroethyl)pyrrolidine to 1-(p-toluenesulfonyl)-1-pentyne, followed by stereoselective reduction of the enamine moiety and reductive desulfonylation.
