The present invention discloses peptide aldehydes which are potent and specific inhibitors of thrombin, their pharmaceutically acceptable salts, pharmaceutically acceptable compositions thereof, and methods of using them as therapeutic agents for disease states in mammals characterized by abnormal thrombosis.
It has been shown that some chalcones are able to inhibit tubulin polymerization, giving cytotoxicity and destruction
of tumoral vasculature. A library of 180 novel chalcone analogs has been synthesized via click chemistry and
screened for their cytotoxicity and tubulin assembly inhibition. 10 out 180 click chalcones displayed low micromolar cytotoxicity
but only compound Nf depicted antitubulin activity. While Nf displayed only micromolar potency this result
shows click-chalcones may be anti-tubulin agents and validate this strategy to search for novel active chemical entities.

polymerization and a potential anticancer activity. However, therapeutic application of CA4 is substantially hindered due to geometric isomerization. In the current study, new cis-restricted Combretastatin A4 analogues containing 1,2,4-triazle in place of the olefinic bond were designed and synthesized. The synthesized compounds were evaluated for their in vitro antiproliferative activity in human hepatocellular
