  • Publication number: 20040122236
    Abstract: The present invention is directed to compositions comprising lysophosphatidic acid analogs and methods of using such analogs as agonist or antagonists of LPA receptor activity. In addition the invention is directed to LPA receptor agonists that vary in the degree of selectivity at individual LPA receptors (i.e. LPA1, LPA2 and LPA3). More particularly the present invention is directed to LPA analogs wherein the glycerol is replaced with ethanolamine and a variety of substitutions have been linked at the second carbon atom.

  • Publication number: 20040110728
    Abstract: The present invention relates to S1P analogs that have activity as S1P receptor modulating agents and the use of such compounds to treat diseases associated with inappropriate S1P receptor activity. The compounds have the general structure (I), wherein R1 is C8-C22 alkyl, C8-C22 alkenyl or R12 is O, or R1 and R12 taken together form an optionally substituted aryl or an optionally substituted heteroaryl; R17 is H, alkyl or alkylaryl; R18 is N or CH; R2 and R3 are independently selected from the group consisting of H, NH2, and OH, with the proviso that at least one of R2 and R3 is NH2; R4 is selected from the group consisting of hydroxyl, phosphate, phosphonate methylene phosphonate, &agr;-substituted methylene phosphonate, thiophoasphate and thiophosphonate; and R5 is C8-C22alkenyl.

  • Publication number: 20040023986
    Abstract: The present invention relates to novel felbamate derivatives and their use to threat neurological diseases such as epilepsy and neuropathic pain, and to treat tissue damage resulting form ischemic events. The felbamate derivatives are modified to prevent the formation of metabolites that are believed responsible for the toxicity associated with felbamate therapy.

  • Patent number: 5622960
    Abstract: Azatoxin and derivatives thereof are illustrative of a new class of antitumor drugs that are topoisomerase II (top 2) inhibitors. The pharmacophore inhibits the catalytic activity of the purified enzyme but does not unwind relaxed or supercoiled DNA. It is nonintercalative and has at least two domains: a quasi-planar polycyclic ring system, which may bind between DNA base pairs, and a pendant substituent thought to interact with the enzyme, with the DNA grooves or with both. In SV40 and c-myc DNA, azatoxin induces numerous double-strand breaks according to a cleavage pattern which differs from those of known top 2 inhibitors. Azatoxin also is a potent inhibitor of tubulin polymerization.

  • Patent number: 5606060
    Abstract: Azatoxin and derivatives thereof are illustrative of a new class of antitumor drugs that are topoisomerase II (top 2) inhibitors. The pharmacophore inhibits the catalytic activity of the purified enzyme but does not unwind relaxed or supercoiled DNA. It is nonintercalative and has at least two domains: a quasiplanar polycyclic ring system, which may bind between DNA base pairs, and a pendant substituent thought to interact with the enzyme, with the DNA grooves or with both. In SV40 and c-myc DNA, azatoxin induces numerous double-strand breaks according to a cleavage pattern which differs from those of known top 2 inhibitors.
