  Cofactor-type inhibitors of inosine monophosphate dehydrogenase via modular approach: Targeting the pyrophosphate binding sub-domain

  摘要：

  Cofactor-type inhibitors of inosine monophosphate dehydrogenase (IMPDH) that target the nicotinamide adenine dinucleotide (NAD) binding domain of the enzyme are modular in nature. They interact with the three sub-sites of the cofactor binding domain; the nicotinamide monophosphate (NMN) binding sub-site (N sub-site), the adenosine monophosphate (AMP) binding sub-site (A sub-site), and the pyrophosphate binding sub-site (P sub-site or P-groove). Mycophenolic acid (MPA) shows high affinity to the N sub-site of human IMPDH mimicking NMN binding. We found that the attachment of adenosine to the MPA through variety of linkers afforded numerous mycophenolic adenine dinucleotide (MAD) analogues that inhibit the two isoforms of the human enzyme in low nanomolar to low micromolar range. An analogue 4, in which 2-ethyladenosine is attached to the mycophenolic alcohol moiety through the difluoromethylenebis(phosphonate) linker, was found to be a potent inhibitor of hIMPDH1 (K-i = 5 nM), and one of the most potent, sub-micromolar inhibitor of leukemia K562 cells proliferation (IC50 = 0.45 mu M). Compound 4 was as potent as Gleevec (IC50 = 0.56 mu M) heralded as a 'magic bullet' against chronic myelogenous leukemia (CML). MAD analogues 7 and 8 containing an extended ethylenebis(phosphonate) linkage showed low nanomolar inhibition of IMPDH and low micromolar inhibition of K562 cells proliferation. Some novel MAD analogues described herein containing linkers of different length and geometry were found to inhibit IMPDH with K-i's lower than 100 nM. Thus, such linkers can be used for connection of other molecular fragments with high affinity to the N- and A-sub-site of IMPDH. (C) 2011 Elsevier Ltd. All rights reserved.

  Nucleosides VI: A Novel and Convenient Synthesis of PurineS-Cyclonucleosides Via Mitsunobu Reaction

  摘要：

  Two representative S-cyclonucleosides, 8,5'-anhydro-2', 3'-O-isopropylidene-8-mercaptoadenosine (3) and 8,2'-anhydro-3',5'-O-(tetraisopropyldisiloxane-1,3-diyl)-8-mercaptoguanosine (8), were prepared in good yields by dropwise addition of one equivalent each of triphenylphosphine and DEAD in DMF into a mixture of 2',3'-O-isopropylidene-8-mercaptoadenosine (2) or 3',5'-O-(tetra-iso-propyldisiloxane-1,3-diyl)-8-mercaptoguanosine (7), respectively, in DMF. Treatment of compound 2 with two equivalents each of triphenylphosphine and DEAD in DMF afforded N-[8,5'-anhydro-2',3'-0-isopropylidene-8-mercaptopurin-6-yl]triphenylphospha-lambda5-azene (4) in 87% yield.

  A series of purine derivatives have been prepared and their in vivo abilities to lower plasma total cholesterol and triglyceride levels, and to elevate high density lipoprotein (HDL) cholesterol levels in hyperlipemic rats have been tested. Some compounds, among which 8-2-(R)-hydroxy-3-[(p-isobutoxycarbonyl)phenoxy]propylthio}adenosine 31, 8-3-[(p-isobutoxy carbonyl)phenoxy]-2-oxopropylthio} adenosine 33 and 8-3-[(p-isobutoxycarbonyl)phenoxy]-2-hydrazonecarboxamidepropylthio} adenosine 36 appear to be the most interesting, have been found to have both the desired profile of activity and no hepatotoxicity, when administered po at 50, 100 or 300 mg/kg. Compounds 31, 33 and 36, orally tested at the same doses in the 15-d test, lower triglyceride and VLDL/LDL (very low density lipoprotein/low density lipoprotein) cholesterol levels by 10-33% and 13-46%, respectively, and increase HDL-associated cholesterol levels by 10-32%. These molecules have been chosen for further pharmacological and toxicological evaluations.
