Publication number: 20070129314Abstract: The present invention provides methods and compositions for modification and regulation of glucose and lipid metabolism, generally to reduce insulin resistance, hyperglycemia, hyperinsulinemia, obesity, hyperlipidemia, hyperlipoprotein-emia (such as chylomicrons, VLDL and LDL), and to regulate body fat and more generally lipid stores, and, more generally, for the improvement of metabolism disorders, especially those associated with diabetes, obesity and/or atherosclerosis.Type: ApplicationFiled: July 17, 2006Publication date: June 7, 2007Applicant: Trustees of Tufts CollegeInventors: William Bachovchin, Andrew Plaut, Daniel Drucker

Patent number: 7157429Abstract: The present invention provides methods and compositions for modification and regulation of glucose and lipid metabolism, generally to reduce insulin resistance, hyperglycemia, hyperinsulinemia, obesity, hyperlipidemia, hyperlipoproteinemia (such as chylomicrons, VLDL and LDL), and to regulate body fat and more generally lipid stores, and, more generally, for the improvement of metabolism disorders, especially those associated with diabetes, obesity and/or atherosclerosis. The compositions of the present invention include dipeptidylpeptidase inhibitors, which are able to inhibit the proteolysis of GLP-1 and accordingly increase the plasma half-life of that hormone. The subject inhibitors may be peptidyl, peptidomimetic (e.g. boronyl peptidomimetics), or non-peptidyl nitrogen containing heterocycles.Type: GrantFiled: July 28, 2000Date of Patent: January 2, 2007Assignee: Trustees of Tufts CollegeInventors: William A. Bachovchin, Andrew G. Plaut, Daniel Drucker

Publication number: 20060089312Abstract: The present invention relates to prodrugs of protease inhibitors, such as inhibitors of proteosome, DPOP IV, FAP? and the like. These “pro-inhibitors” are activated, i.e., cleaved by an “activated protease” to release an active inhibitor moiety in proximity to a “target protease”. The identity of activating protease and target protease can be the same (such pro-inhibitors being refered to as “Target-Activated Smart Protease Inhibitors” or “TASPI”) or different (e.g., “Target-Directed Smart Protease Inhibitors” or “TDSPI”). After activation of the pro-inhibitor, the active inhibitor moiety can self-inactive by, e.g., intramolecular-cyclization or cis-trans isomerization.Type: ApplicationFiled: April 30, 2003Publication date: April 27, 2006Inventor: William Bachovchin
-
Publication number: 20060069030Abstract: The present invention provides peptidomimetics derived from Apolipoprotein A-I, which is useful for beneficially influencing lipid parameters and/or plasma cholesterol levels. The invention also provides pharmaceutical compositions and methods of treatment for elevated levels of plasma cholesterol.Type: ApplicationFiled: July 15, 2005Publication date: March 30, 2006Applicant: Trustees of Tufts CollegeInventor: William Bachovchin
-
Publication number: 20050202027Abstract: Synthetic crosslinking homobivalent and heterobivalent compounds have been designed and developed. These compounds are low in molecular weight, have antagonistic or agonistic activity, and induce the association between two identical or similar natural receptors (homobivalent compounds) or induce the association between two different natural receptors (heterobivalent compounds).Type: ApplicationFiled: January 6, 2005Publication date: September 15, 2005Inventor: William Bachovchin
-
Publication number: 20050203027Abstract: The present invention relates to inhibitors of post-proline cleaving enzymes, such as inhibitors of dipeptidyl peptidase IV, as well as pharmaceutical compositions thereof, and methods for using such inhibitors. In particular, the inhibitors of the present invention are improved over those in the prior art by selection of particular classes of sidechains in the P1 and/or P2 position of the inhibitor that contain a carboxylic acid moiety. The compounds of the present invention can have a better therapeutic index, owing in part to reduced toxicity and/or improved specificity for the targeted protease.Type: ApplicationFiled: February 23, 2005Publication date: September 15, 2005Applicant: Trustees of Tufts CollegeInventors: William Bachovchin, Hung-sen Lai, Wengen Wu
-
