Novel matrix metalloproteinase inhibitors: Generation of lead compounds by the in silico fragment-based approach

Generation of structurally new matrix metalloproteinase inhibitors was successfully carried out using an in silico technique. In order to identify the small fragment interacting with residues in the S1′ pocket of MMP-1 through hydrogen bonds, we performed in silico screening using the LUDI program. As a result, acetyl-l-alanyl-(N-methyl)amide (Ac-l-Ala-NHMe) was selected to link with another fragment, hydroxamic acid that interacted with catalytic zinc. By this approach, the l-glutamic acid derivative 2b was discovered to be a new type of matrix metalloproteinase inhibitor. Further transformation to reduce its peptidic nature and improve activity yielded nonpeptidic lead compounds as inhibitors of MMP-1, -2, -3, and -9.

Fucose derivatives, drugs containing the same as active ingredient, and intermediates for producing the same

A compound of the formula (I): STR1 wherein X1 is a group of one of the following formulae (1), (2) and (3): STR2 R1 is a branched long chain alkyl group, R2 is --CONHR3, a carboxyl group or a hydrogen atom, n is an integer of 0, 1 or 2, and R3 is a lower alkyl group or a phenyl group, or a pharmaceutically acceptable salt thereof, which is useful as a selectin inhibitor, and can be used in the prophylaxis or treatment of various inflammatory diseases such as inflammatory dermatitis (e.g., atopic dermatitis, contact hypersensitivity, photodermatosis, etc.), autoimmune chronic diseases (e.g. rheumatoid arthritis, chronic thyroiditis, etc.), and ischemia-reperfusion injury.

Studies on selection blockers. 5. Design, synthesis, and biological profile of sialyl Lewis x mimetics based on modified serine-glutamic acid dipeptides.

We have rationally designed a sLe(x) mimetic based on molecular modeling, synthesized type II and type II' beta-turn dipeptides (3a,b), and evaluated their biological profiles both in vitro and in vivo. Against E-selectin-sLe(x) binding, the type II beta-turn dipeptide L-Ser-D-Glu 3a (IC50, 13 microM) and the type II' beta-turn dipeptide D-Ser-L-Glu 3b (IC50, 5.5 microM) were 20-100-fold more potent blockers than sLe(x) (1; IC50, 600 microM) and a 3'-sulfated Le(x) analog (2; IC50, 280 microM). On the other hand, other stereoisomers, such as L-Ser-L-Glu 3c and D-Ser-D-Glu 3d, were very weak blockers, with IC50 > 1000 microM for both 3c,d. Against the P- and L-selectins, despite much different stereochemistry of compounds 3a-d, the dipeptides 3a-d were all more potent blockers than either sLe(x) or compound 2. Interestingly, compound 3b provided significant in vivo efficacy against an immunoglobulin E-mediated skin reaction in a mouse model. These findings indicate that sLe(x) mimetics with type II and type II' beta-turn dipeptides could be useful in the design of an active selectin blocker in vitro and/or in vivo.
