  Inhibition of monoamine oxidase by 8-[(phenylethyl)sulfanyl]caffeine analogues

  摘要：

  In a previous study we have investigated the monoamine oxidase (MAO) inhibitory properties of a series of 8-sulfanylcaffeine analogues. Among the compounds studied, 8-[(phenylethyl) sulfanyl] caffeine (IC50 = 0.223 mu M) was found to be a particularly potent inhibitor of the type B MAO isoform. In an attempt to discover potent MAO inhibitors and to further examine the structure-activity relationships (SAR) of MAO inhibition by 8-sulfanylcaffeine analogues, in the present study a series of 8-[(phenylethyl)sulfanyl] caffeine analogues were synthesized and evaluated as inhibitors of human MAO-A and -B. The results document that substitution on C3 and C4 of the phenyl ring with alkyl groups and halogens yields 8-[( phenylethyl) sulfanyl] caffeine analogues which are potent and selective MAO-B inhibitors with IC50 values ranging from 0.017 to 0.125 mu M. The MAO inhibitory properties of a series of 8-sulfinylcaffeine analogues were also examined. The results show that, compared to the corresponding 8-sulfanylcaffeine analogues, the 8-sulfinylcaffeins are weaker MAO-B inhibitors. Both the 8-sulfanylcaffeine and 8-sulfinylcaffeine analogues were found to be weak MAO-A inhibitors. This study also reports the MAO inhibition properties of selected 8-[(phenylpropyl) sulfanyl] caffeine analogues. (C) 2012 Elsevier Ltd. All rights reserved.

  A highly efficient, odourless and two-step three-component process for one-pot synthesis of some 8-alkylmercaptocaffeine derivatives has been described. The catalyst-free three-component reaction of alkyl bromides, thiourea, and 8-bromocaffeine gave 8-alkylmercaptocaffeine products in excellent to quantitative yields. In addition, the impact of parameters on sample reaction is discussed.

  damage (P > 0.05). Computational studies showed that H-bond formation between the nitrogen atom in pyrazolo[4,3-D] pyrimidine moiety with Gln817 and creating a hydrophobic cavity result in the stability of the alkyl group in the PDE5A active site. We found that synthesized 8-alkylmercaptocaffeine derivatives induced cell death in different cancer cells through the cGMP pathway. These findings will help

  In a recent study it was shown that 8-benzyloxycaffeine analogues act as potent reversible inhibitors of human monoamine oxidase (MAO) A and B. Although the benzyloxy side chain appears to be particularly favorable for enhancing the MAO inhibition potency of caffeine, a variety of other C8 oxy substituents of caffeine also lead to potent MAO inhibition. In an attempt to discover additional C8 substituents of caffeine that lead to potent MAO inhibition and to explore the importance of the ether oxygen for the MAO inhibition properties of C8 oxy-substituted caffeines, a series of 8-sulfanyl-and 8-aminocaffeine analogues were synthesized and their human MAO-A and -B inhibition potencies were compared to those of the 8-oxycaffeines. The results document that the sulfanylcaffeine analogues are reversible competitive MAO-B inhibitors with potencies comparable to those of the oxycaffeines. The most potent inhibitor, 8-[(4-bromophenyl)methyl]sulfanyl}caffeine, exhibited an IC50 value of 0.167 mu M towards MAO-B. While the sulfanylcaffeine analogues also exhibit affinities for MAO-A, they display in general a high degree of MAO-B selectivity. The aminocaffeine analogues, in contrast, proved to be weak MAO inhibitors with a number of analogues exhibiting no binding to the MAO-A and -B isozymes. The results of this study are discussed with reference to possible binding orientations of selected caffeine analogues within the active site cavities of MAO-A and -B. MAO-B selective sulfanylcaffeine derived inhibitors may act as lead compounds for the design of antiparkinsonian therapies. (C) 2011 Elsevier Ltd. All rights reserved.
