Determination and correlation of solubility of tris(3-hydroxypropyl) phosphine oxide in selected solvents

The solubility of tris(3-hydroxypropyl)phosphine oxide (THPPO) in selected solvents was measured by a static analytic method over the temperature range from (293 to 328) K in methanol, ethanol, n-propyl alcohol, isopropyl alcohol, n-butyl alcohol, isobutyl alcohol, acetone, and a binary solvent mixture of ethanol + acetone. Several widely used thermodynamic models, such as the empirical equation and the Buchowski-Ksiazaczak (λh), Scatchard-Hildebrand, Wilson, nonrandom two-liquid (NRTL), and universal quasichemical (UNIQUAC) equations were applied to represent the measurement results. The binary interaction parameters of the above models were found to have a linear dependency on temperature, and the coefficients were regressed. The results show that all of these models can satisfactorily reproduce the experimental data and the NRTL equation can provide the best correlation with an overall relative standard deviation of 0.46 %.

NOVEL CYTOTOXIC AGENTS FOR CONJUGATION OF DRUGS TO CELL BINDING MOLECULE

Provided are cytotoxic agents, pyrrolo[2,1-c][1,4]benzodiazepine (PBD) derivatives, their conjugates with a cell-binding agent, the preparation and the therapeutic uses in the targeted treatment of cancers, autoimmune disorders, and infectious diseases.

Tris(3-hydroxypropyl)phosphine (THPP): A mild, air-stable reagent for the rapid, reductive cleavage of small-molecule disulfides

Tris(3-hydroxypropyl)phosphine (THPP) is demonstrated to be a versatile, water-soluble and air-stable reducing agent, allowing for the rapid, irreversible reductive cleavage of disulfide bonds in both aqueous and buffered aqueous-organic media. The reagent shows exceptional stability at biological pH under which condition it permits the rapid reduction of a wide range of differentially functionalized small-molecule disulfides.

Selective two-phase-hydrogenation of sorbic acid with novel water soluble ruthenium complexes

Neutral and cationic water soluble Cp*-ruthenium-complexes of the type [Cp*Ru(CO)Cl(PR3)] and [Cp*Ru(CO)(PR3)]CF3SO3 (R=CH2OH, (CH2)3OH, Ph-m-SO3Na) have been synthesized for the first time and have been used as catalysts in two-phase-hydrogenations. The neutral complexes have been fully characterized. But the cationic complexes which have not been isolated are effective catalysts for the selective hydrogenation of sorbic acid in water/n-heptane leading to the formation of cis-3-hexenoic acid and trans-3-hexenoic acid.

Method of oxidizing tertiary-alkyl phosphines

Tertiary-alkyl phosphines, such as tris-(3-hydroxypropyl) phosphine may be oxidized by heating in the presence of water and between about 0.1 and about 10% by weight of an acid catalyst at a temperature above about 100° C.
