The present invention comprises small molecular weight, non-peptidic inhibitors of formulae I-VII of Protein Tyrosine Phosphatase 1 (PTP1) which are useful for the treatment and/or prevention of Non-Insulin Dependent Diabetes Mellitus (NIDDM).

best calpain I inhibitor in this study was Z-Leu-Nva-CONH-CH2-2-pyridyl (Ki = 19 nM). The peptide alpha-keto amide Z-Leu-Abu-CONH-(CH2)2-3-indolyl was the best inhibitor for cathepsinB (Ki = 31 nM). Some compounds acted as specific calpaininhibitors, with comparable activity on both calpains I and II and a lack of activity on cathepsinB (e.g., 40, 42, 48, 70). Others were specific inhibitors for
