These compounds are useful as medicaments such as a fibrosis inhibitor for organs or tissues.
Cobalt-catalyzed activation of methylthio-substituted N-heterocycles facilitates either cross-coupling reactions with aryl- or benzylzinc compounds or synthesis of the corresponding zinc compounds.
This invention relates to substituted heteroanilide compounds which are modulators, agonists or antagonists, of the CCR5 receptior. In addition, this invention relates to the treatment and prevention of disease states mediatd by CCR5.
A new class of small molecules, with an unprecedented trifluorothiazoline scaffold, were synthesized and their pro‐apoptotic activity was evaluated. With an EC50 in the low micromolar range, these compounds proved to be potent inducers of apoptosis in a broad spectrum of tumor cell lines, regardless of the functional status of p53. Fast structure–activity relationship studies allowed the preparation
