A platform for designing HIV integrase inhibitors. Part 1: 2-Hydroxy-3-heteroaryl acrylic acid derivatives as novel HIV integrase inhibitor and modeling of hydrophilic and hydrophobic pharmacophores

We present a novel series of HIV integrase inhibitors, showing IC50s ranging from 0.01 to over 370 muM in an enzymatic assay. Furthermore, pharmacophore modeling study for the inhibitors was carried out to elucidate the structure-activity relationships. Finally, we found a 3D-pharmacophore model, which is composed of a hydrophilic and a hydrophobic domain, providing valuable information for designing other novel types of integrase inhibitors.

Studies on antiulcer drugs. V. Synthesis and antiulcer activity of aralkylbenzazoles

A series of 2-alkylamino-5- or 6-aralkyl-substituted benzazoles were synthesized and tested for histamine H2-receptor antagonist and anti-stress ulcer activities. These new compounds showed little or no histamine H2-receptor antagonist activity in contrast to imidazo[1,2-a]pyridine analogues (I). On antiulcer assay, however, some pyridine derivatives (II) exerted higher activity than the reference compounds, sofalcone, sucralfate and cimetidine. The structure activity relationships of these compounds are discussed.

Geometries and tautomerism of OHN hydrogen bonds in aprotic solution probed by H/D isotope effects on 13C NMR chemical shifts

The 1H and 13C NMR spectra of 17 OHN hydrogen-bonded complexes formed by CH313COOH(D) with 14 substituted pyridines, 2 amines, and N-methylimidazole have been measured in the temperature region between 110 and 150 K using CDF3/CDF2Cl mixture as solvent. The slow proton and hydrogen bond exchange regime was reached, and the H/D isotope effects on the 13C chemical shifts of the carboxyl group were measured. In combination with the analysis of the corresponding 1H chemical shifts, it was possible to distinguish between OHN hydrogen bonds exhibiting a single proton position and those exhibiting a fast proton tautomerism between molecular and zwitterionic forms. Using H-bond correlations, we relate the H/D isotope effects on the 13C chemical shifts of the carboxyl group with the OHN hydrogen bond geometries.

Oxidative degradation of a novel AMP/AEP blend designed for CO2 capture based on partial oxy-combustion technology

Solvent degradation and volatile compound emissions are two of the major concerns about the deployment of carbon capture technologies based on chemical absorption. In this context, partial oxy-combustion might reduce the solvent degradation due to the use of a higher CO2 concentrated flue gas. This work evaluates the oxidative degradation of a novel AMP/AEP blend, namely POS #1, under partial oxy-combustion conditions. The effects of temperature and flue gas composition were evaluated in terms of solvent loss, degradation rates, NH3 emissions and degradation products. The experiments were set at temperatures up to 70 C and two levels of O2 concentration ? 3%v/v and 6%v/v. The CO2 concentration of the flue gas ranged between 15%v/v and 60%v/v CO2. The novel solvent POS#1 showed high resistance to degrade and resulted in lower degradation rates than MEA in all the operating conditions evaluated in this work. The maximum degradation of AEP and AMP was 24% and 19%, respectively. MEA degraded almost double under the same conditions. Temperature and O2 concentration enhanced the oxidative degradation of POS #1. However, the use of higher CO2 concentration in the flue gas led to lower degradation rates of AEP and AMP and hence oxidative degradation was partially inhibited under partial oxy-combustion conditions. The presence of higher CO2 content in the flue gas decreased the NH3 production and a 70% reduction of its emissions was achieved as the CO2 concentration shifted from 15%v/v to 60%v/v. Other major degradation compounds such as formate and 2,4-lutidine were also decreased. New degradation products were not identified so that the suggested degradation pathways proposed in the literature were not influenced by the presence of higher CO2 concentrations.

The detection of chemically induced chromosomal malsegregation in Saccharomyces cerevisiae D61.M: A literature survey (1984-1990)

Our objective is to summarize the published data obtained with a recently developed tester strain suitable for the detection of chromosomal malsegregation in yeast. Results from 25 papers were reviewed in which numerical data for 111 chemicals tested in Saccharomyces cerevisiae D61.M are reported (a total of 316 independent tests; 279 acceptable, 37 not meeting our criteria). Of the 111 compounds analyzed 43 compounds are positive for chromosomal malsegregation, 56 compounds are negative and 12 compounds do not meet our criteria for acceptance (inconclusive). Of the 43 compounds judged positive 5 (acetone, acetonitrile, benzonitrile, ethylacetate and propionitrile) were only positive using a cold interruption protocol. Recommendations are made for standardization of methods and protocols for screening purposes. Finally, a comparison with in vitro tubulin assembly data using mammalian tubulin is presented.

Synthesis, reactivity, structural aspects, and solution dynamics of cyclopalladated compounds of N,N?,N??-Tris(2-anisyl)guanidine

N,N?,N??-Tris(2-anisyl)guanidine, (ArNH)2C=NAr (Ar = 2-(MeO)C6H4), was cyclopalladated with Pd(OC(O)R)2 (R = Me, CF3) in toluene at 70 C to afford palladacycles [Pd{kappa2(C,N)-C6H 3(OMe)-3(NHC(NHAr)(=NAr))-2}(mu-OC(O)R)]2 (R = Me (1a) and CF3 (1b)) in 87% and 95% yield, respectively. Palladacycle 1a was subjected to a metathetical reaction with LiBr in aqueous ethanol at 78 C to afford palladacycle [Pd{kappa2(C,N)-C6H 3(OMe)-3(NHC(NHAr)(=NAr))-2}(mu-Br)]2 (2) in 90% yield. Palladacycle 2 was subjected to a bridge-splitting reaction with Lewis bases in CH2Cl2 to afford the monomeric palladacycles [Pd{kappa2(C,N)-C6H3(OMe)-3(NHC(NHAr)(=NAr))- 2}Br(L)] (L = 2,6-Me2C5H3N (3a), 2,4-Me 2C5H3N (3b), 3,5-Me2C 5H3N (3c), XyNC (Xy = 2,6-Me2C 6H3; 4a), tBuNC (4b), and PPh3 (5)) in 87-95% yield. Palladacycle 2 upon reaction with 2 equiv of XyNC in CH 2Cl2 afforded an unanticipated palladacycle, [Pd{kappa2(C,N)-C(=NXy)(C6H3(OMe)-4)-2(N= C(NHAr)2)-3}Br(CNXy)] (6) in 93% yield, and the driving force for the formation of 6 was ascribed to a ring contraction followed by amine-imine tautomerization. Palladacycles 1a,b revealed a dimeric transoid in-in conformation with “open book” framework in the solid state. In solution, 1a exhibited a fluxional behavior ascribed to the six-membered “(C,N)Pd” ring inversion and partly dissociates to the pincer type and kappa2-O,O?-OAc monomeric palladacycles by an anchimerically assisted acetate cleavage process as studied by variable-temperature 1H NMR data. Palladacycles 3a,b revealed a unique trans configuration around the palladium with lutidine being placed trans to the Pd-C bond, whereas cis stereochemistry was observed between the Pd-C bond and the Lewis base in 4a (as determined by X-ray diffraction data) and 5 (as determined by 31P and 13C NMR data). The aforementioned stereochemical difference was explained by invoking relative hardness/softness of the donor atoms around the palladium center. In solution, palladacycles 3a-c exist as a mixture of two interconverting boat conformers via a planar intermediate without any bond breaking due to the six-membered “(C,N)Pd” ring inversion, whereas palladacycles 4a,b and 5 exist as a single isomer, as deduced from detailed 1H NMR studies.
