    摘要: The present invention is a novel class of compounds useful in thermally-responsive record material of the type comprising a substrate having provided thereon in substantially contiguous relationship an electron donating dye precursor, and an acidic developer material. The novel compound of the invention is a compound of the formula (I), wherein P is selected from (II) and (III) wherein R1 is selected from hydrogen, alkoxy, and aralkoxy; wherein R2 is aralkoxyalkoxy when P is phenyl, and R2 is selected from aralkoxyalkoxy or alkoxyalkoxy when P is naphthyl. Said alkyl moieties are each independently from one to eight carbons, said aryl moieties each independently being unsubstituted or substituted by alkyl (C1-C8), alkoxy (C1-C8) or halogen. The compounds of the invention enable manufacture of thermally responsive record material of the invention having the unexpected and remarkable properties of enhanced image intensity or density, and/or improved thermal response. The compounds of the invention also find use in diverse applications such as emolients and softening agents for creams, lots and cosmetics.

    摘要: The original synthesis of combretastatin A-2 (1a) was modified to provide an efficient scale-up procedure for obtaining this antineoplastic stilbene. Subsequent conversion to a useful prodrug was accomplished by phosphorylation employing in situ formation of dibenzylchlorophosphite followed 30 by cleavage of the benzyl ester protective groups with bromotrimethylsilane to afford phosphoric acid intermediate 11. The latter was immediately treated with sodium methoxide to complete a practical route to the disodium phosphate prodrug (2a). The phosphoric acid precursor (11) of phosphate 2a was employed in a parallel series of reactions to produce a selection of metal and ammonium cation prodrug candidates. Each of the phosphate salts (2a-q) was evaluated with respect to relative solubility behavior, cancer cell growth inhibition, and antimicrobial activity.

    摘要: Novel diphenylethylene and styrenes are provided which are administered orally to decrease blood glucose levels in rats. The glucose tolerance in insulin resistant rats is also shown, as well as lowering of triglyceride levels in serum insulin resistant, hyperinsulinemic and hypertriglycedemic rats. The compounds are orally effective anti-diabetic agents that potentially may reduce abnormality of glucose and lipid metabolism in diabetes.
