  Geometrically and Conformationally Restrained Cinnamoyl Compounds as Inhibitors of HIV-1 Integrase:  Synthesis, Biological Evaluation, and Molecular Modeling

  摘要：

  Various cinnammoyl-based structures were synthesized and tested in enzyme assays as inhibitors of the HIV-1 integrase (IN). The majority of compounds were designed as geometrically or conformationally constrained analogues of caffeic acid phenethyl ester (CAPE) and were characterized by a syn disposition of the carbonyl group with respect to the vinylic double bond. Since the cinnamoyl moiety present in flavones such as quercetin (inactive on HIV-1-infected cells) is frozen in an anti arrangement, it was hoped that fixing our compounds in a syn disposition could favor anti-HIV-1 activity in cell-based assays. Geometrical and conformational properties of the designed compounds were taken into account through analysis of X-ray structures available from the Cambridge Structural Database. The polyhydroxylated analogues were prepared by reacting 3,4-bis(tetrahydropyran-2-yloxy)benzaldehyde with various compounds having active methylene groups such as 2-propanone, cyclopentanone, cyclohexanone, 1,3-diacetylbenzene, 2,4-dihydroxyacetophenone, 2,3-dihydro-1-indanone, 2,3-dihydro-1,3-indandione, and others. While active against both 3'-processing and strand-transfer reactions, the new compounds, curcumin included, failed to inhibit the HIV-1 multiplication in acutely infected MT-4 cells. Nevertheless, they specifically inhibited the enzymatic reactions associated with IN, being totally inactive against other viral (HIV-1 reverse transcriptase) and cellular (RNA polymerase II) nucleic acid-processing enzymes. On the other hand, title compounds were endowed with remarkable antiproliferative activity, whose potency correlated neither with the presence of catechols (possible source of reactive quinones) nor with inhibition of topoisomerases. The SARs developed for our compounds led to novel findings concerning the molecular determinants of IN inhibitory activity within the class of cinnamoyl-based structures. We hypothesize that these compounds bind to IN featuring the cinnamoyl residue C=C-C=O in a syn disposition, differently from flavone derivatives characterized by an anti arrangement about the same fragment. Certain inhibitors, lacking one of the two pharmacophoric catechol hydroxyls, retain moderate potency thanks to nonpharmacophoric fragments (i.e., a m-methoxy group in curcumin) which favorably interact with an "accessory" region of IN. This region is supposed to be located adjacent to the binding site accommodating the pharmacophoric dihydroxycinnamoyl moiety. Disruption of coplanarity in the inhibitor structure abolishes activity owing to poor shape complementarity with the target or an exceedingly high strain energy of the coplanar conformation.

  We previously reported the design and discovery of three series of 5-carbon linker-containing mono-carbonyl analogs of curcumin (MCACs) as excellent anti-inflammatory agents. In continuation of our ongoing research, we designed and synthesized the fourth series of MCACs, whose central linker is a piperid-4-one. Their inhibitory effects against IL-6 production were evaluated in lipopolysaccharide (LPS)-stimulated macrophages. Among them, compounds F8, F29, F33, F35, and F36 exhibited the IC50 values under 5 mu M. The structure-activity relationship was discussed. Mechanistically, F35 and F36 dose-dependently prevented LPS-induced NF-kappa B and ERK activation. Finally, pretreatment with F35 and F36 significantly protected the C57B/L6 mice from LPS-induced septic death. Together, these data present a series of new analogs of curcumin as promising anti-inflammatory agents. (C) 2013 Elsevier Ltd. All rights reserved.

  Curcumin is the active ingredient of turmeric powder with a variety of biological activities including anti-oxidative activity. In order to find more active antioxidants with curcumin as the lead compound we synthesised a series of enone analogues of curcumin. The present work studied and compared the capacity of curcumin-directed analogues to scavenge 2,2-diphenyl-1-picrylhydrazyl (DPPH center dot) and protect human red blood cells (RBCs) from oxidative haemolysis. It was found that these compounds which bear o-diphenoxyl and o-dimethoxyphenoxyl groups exhibited significantly higher DPPH center dot-scavenging and anti-haemolysis activities than those which bear no such groups. In contrast to curcumin analogues that retained the 7-carbon spacer, the compounds with a 5-carbon linker had lower activity. in the case of the latter, the introduction of a ring further decreased DPPH center dot-scavenging activity. However, the introduction of a ring did increase anti-haemolysis activity, suggesting that the lipophilicity of these compounds might play an important role in the antioxidant activity.

  Natural curcumin (1), demethoxycurcumin (2) and bisdemethoxycurcumin (3) isolated from Curcuma longa (turmeric), and synthetic curcumin analogs (A(1-7), B1-7, C1-6 and D1-7) were evaluated in vitro for the a-glucosidase inhibitory activity via UV and circular dichroism (CD) spectroscopy. The results indicated that natural curcuminoid compound 3 showed a remarkable inhibitory effect with IC50 of 23.0 mu M, and the synthetic compounds A(2), B-2, C-2 and D-2 showed potent inhibitory effects with IC50 of 2.8, 2.6, 1.6 and 8.2 mu M, respectively. Kinetic study exhibited that the mechanism of alpha-glucosidase inhibition of both 3 and C-2 was non-competitive. The structure activity relationship revealed that the ortho dihydroxyl groups could form a more tight interaction with a-glucosidase to exert more potential inhibitory activities.
