A series of cinnamylindoline derivatives were synthesized, and their factor Xa (FXa) inhibitory activities and selectivity over trypsin were evaluated. Among them, some novel derivatives showed potent FXa inhibitory activities and good selectivity over trypsin. Especially, (E)-2-5-[1-(acetimidoyl)piperidin-4-yloxy]-2-[2-(5-amidino-2-hydroxyphenyl)ethen-1-yl]indolin-1-ylsulfonyl}acetic acid (22f) having 2-hydroxycinnamyl moiety exhibited the most potent FXa inhibitory activity in vitro. Furthermore, 22f also exhibited potent anticoagulant activities in vitro.

The reactions of aryl acetals/ketals and triphenylphosphine hydrobromide gave the corresponding aldehydes/ketones and alkyl phosphonium bromides. This reaction was applied to convert acetals/ketals to the corresponding aldehydes/ketones under an anhydrous and convenient condition (50 oC, 5 min, up to 90% yield), and acid sensitive functional groups were compatible.

Conjugates of epothilones and epothilone derivatives (as effectors) with suitable saccharides or saccharide derivatives (as recognition units) are described. Their production is carried out by the recognition units being reacted with suitable linkers, and the compounds that are produced are conjugated to the effectors. The pharmaceutical use of the conjugates for treating proliferative or angiogenesis-associated processes is described.
particularly to opto-electronic devices. However, there is limited information regarding the synthesis of glass-forming metal complexes. Herein, a library of salicylaldehyde imine derivatives incorporating mexylaminotriazine substituents were synthesized, from which respective complexes with various first-row transitionmetals were prepared. The resulting compounds were characterized and evaluated for their glass-forming
