Abstract:
The effect temperature has on the composition of a vapor phase passed through a thermal field after the evaporation of a mechanical mixture of the powders of cadmium and zinc selenotelluride is studied. It is found that the composition of the vapor phase can be changed throughout the range of concentrations by varying the temperature. The results of the study are satisfactorily explained by the effect temperature has on the particle distribution function in correspondence to the weights of the molecules constituting the mixture. There were virtually no molecules of the evaporated substance in

Abstract:
A set of 2-aryl-9-H or methyl-6-morpholinopurine derivatives were synthesized and assayed through radioligand binding tests at human A1, A2A, A2B, and A3 adenosine receptor subtypes. Eleven purines showed potent antagonism at A1, A3, dual A1/A2A, A1/A2B, or A1/A3 adenosine receptors. Additionally, three compounds showed high affinity without selectivity for any specific adenosine receptor. The structure-activity relationships were made for this group of new compounds. The 9-methylpurine derivatives were generally less potent but more selective, and the 9H-purine derivatives were more potent bu

A novel peptide-linked triacridine (2) of the type‡ ( Acr )-A-c( Acr )-B-( Acr ) has been synthesized in which the central trifunctional group (-c<) is 2,4-diaminobutyric acid (A2bu), spacer A is - γAbu-Tyr-Lys-Lys-Gly - and spacer B is - Gly-Gly-Gly-Gly-NH (CH2)3NH-. This DNA-binding ligand was prepared by solution phase methodology in 12 steps from known compounds.

Abstract:
Adenosine receptors are a subfamily of highly-conserved G-protein coupled receptors. They are found in the membranes of various human cells and play many physiological functions. Blood platelets express two (A2A and A2B) of the four known adenosine receptor subtypes (A1, A2A, A2B, and A3). Agonization of these receptors results in an enhanced intracellular cAMP and the inhibition of platelet activation and aggregation. Therefore, adenosine receptors A2A and A2B could be targets for anti-platelet therapy, especially under circumstances when classic therapy based on antagonizing the purinergic r

Abstract:
A series of amide compounds (A2D1-A2D6) were synthesized based on sulfathiazole by converting it to diazonium salt using NaNO2 and concentrated HCl via diazotization reaction. This reaction was followed by coupling reaction with vanillic acid in alkaline medium to generated azo compound 4-hydroxy-3-methoxy-5-((4-(N-(thiazol-2-yl)sulfamoyl)phenyl)diazenyl)-benzoic acid (A2). Compound A2 was reacted with substituted aromatic amines such as 2-amino-4,6-dimethylpyridine, sulfamerazine, sulfadiazine, sulfanilamide, sulfathiazole, and sulfanilic acid to form corresponding amides using DCC as couplin

Abstract:
Porphyrins may serve as the active charge-storage medium in memory chips. A series of 14 porphyrins (trans-A2B2, trans-AB2C, or A4 type; free base, copper or zinc chelate) has been synthesized for investigation of metal deposition on porphyrin monolayers. Each trans-AB2C porphyrin is equipped with a surface attachment group and a distal functional group (or flanking functional groups). The surface attachment groups include S-acetylthiomethyl, hydroxymethyl, TMS-ethynyl, allyl, and triallylmethyl; the functional groups include amino, cyano, dipyrrin-5-yl, formyl, and nitro; all of which are att

Abstract:
A series of chiral A4, A2B2, and AB3 porphyrins bearing proline moieties at the meso-phenyl group has been synthesized. Photostability studies revealed that the number of L-proline units and their position on meso-phenyl rings strongly influence the decomposition rate of the catalyst. 5,10,15-Tris(mesityl)-20-(3-prolinanilidylphenyl)-21,23H-porphyrin is the most stable while porphyrin bearing four 3-prolinanilidylphenyl substituents completely decomposes in CHCl 3 within 3 h. Singlet oxygen quantum yields of the conjugates were determined by measuring the peak areas of the NIR emission of 1 O

Abstract:
Metal hydrides are an interesting group of chemical compounds, able to store hydrogen in a reversible, compact and safe manner. Among them, A2B7-type intermetallic alloys based on La-Mg-Ni have attracted particular attention due to their high electrochemical hydrogen storage capacity (∼400 mAh/g) and extended cycle life. However, the presence of Mg makes their synthesis via conventional metallurgical routes challenging. Replacing Mg with Y is a viable approach. Herein, we present a systematic study for a series of compounds with a nominal composition of La2-xYxNi6.50Mn0.33Al0.17, x = 0.33, 0.6
