Protein kinase B (PknB) is an essential serine/threonine protein kinase required for Mycobacterium tuberculosis (M. tb) cell division and cell-wall biosynthesis. A high throughput screen using PknB identified a (E)-4-oxo-crotonic acid inhibitor, named YH-8, which was used as a scaffold for SAR investigations. A significant improvement in enzyme affinity was achieved. The results indicated that the

The conjugate addition of indoles to 4-aryl-4-oxobut-2-enoates was achieved with FeCl3 as a catalyst under mild conditions. The reaction was highly regioselective and afforded a variety of new 3-substituted indoles in good to excellent yields.

3-(4-Phenoxybenzoyl) propionic acids were prepared and tested for hypolipidemic activity in normal rats. A structure-activity relationship study showed that the 2-acetylthio derivative had hypolipidemic activity. Among these compounds, 2-acetylthio-[3-(4-chlorophenoxy) benzoyl] propionic acid possessed very potent activity.
