Abstract: Lysophosphatidic acid acyltransferase-beta (LPAAT-?) catalyzes the production of phosphatidic acid (PA) from lysophosphatidic acid (LPA). The lipid cofactor PA contributes to the activation of c-Raf, BRAF, mTOR and PKC-?. LPAAT-? expression is a prognostic factor in gynecologic malignancies and is being investigated as a therapeutic target in a variety of tumor types. A class of thiosemicarbazones was identified as inhibitors of LPAAT-? from a screen of a library of small molecules. A focused library of thiosemicarbazones derivatives was prepared and led to the development of compounds which potently inhibit LPAAT-? and inhibit the growth of MiaPaCa2 human pancreatic cancer cells.

Abstract: Compounds and associated methods for inhibiting a protein tyrosine phosphatase. By a combination of experimental and virtual screenings of the NCI Diversity Set chemical library, NSC-87877 and NSC-117199 have been identified as Shp2 PTP inhibitors. Significantly, NSC-87877 is active in cell-based assays and has no detectable off-target effects in the EGF-stimulated Erk 1/2 activation pathway. Additionally, a number of analogs of NSC-117199 have been produced. These analogs exhibit enhanced protein tyrosine phosphatase inhibition and are found to be potent and/or selective inhibitors of Shp1 and/or Shp2 protein tyrosine phosphatases.

Abstract: The object of the present invention is the development of new chiral auxiliaries for improved &bgr;-lactam formation that control both the diastereoselectivity of &bgr;-lactam formation and which can be removed without destruction of the sensitive azetidinone ring, providing valuable intermediates for coupling to the C-13 hydroxyl group of anti-tumor taxanes, such as paclitaxel. Further, the object of the present invention is enantiomerically pure (S)-(−)-1-(p-methoxy-phenyl)propyl-1-amine.
