PDE7-selective and dual inhibitors: Advances in chemical and biological research

Phosphodiesterase 7 (PDE7) is an intracellular enzyme that specifically hydrolyzes the second messenger, cyclic-3?,5?-adenosine monophosphate (cAMP), into inactive noncyclic nucleotide, 5?-AMP. To date, many structurally diverse compounds with PDE7 inhibitory properties have been described, including selective PDE7 inhibitors, dual PDE4/PDE7, PDE7/PDE8, and PDE7/GSK-3 inhibitors, and non-selective PDE inhibitors with high affinity for PDE7. Inhibitors of PDE7 have provided beneficial effects in animal models of inflammatory and neurological disorders, including Alzheimer?s disease, Parkinson?s disease, multiple sclerosis, and many others. This review is a comprehensive summary of the current state-of-the-art in the field of design and synthesis of PDE7 inhibitors, their physicochemical properties, biological evaluation, and structure-activity relationships as well as it highlights the updated evidence for a potential therapeutic utility of these compounds. Moreover, new approaches to obtain more effective and safer PDE7 inhibitors than those available now are presented.

Synthesis of 1,1?-ferrocene diformates bearing isoxazole moiety and preliminarily cytotoxicity to A549, HCT116 and MCF-7 cell lines

Background: Ferrocene is a potential pharmacophore for drug design and drug discovery. Methods: Based on our previous good achievements (Med. Chem. commun., 2014,7,968-972), nineteen novel structures of 1,1?-ferrocene diformates bearing isoxazole moiety (3a-3s) were firstly synthesized in the current work and characterized by 1H NMR, 13C NMR, ESI-MS. Then, their cytotoxicity to A549, HCT116 and MCF-7 cell lines was evaluated using the MTT method. Results: The results showed that most compounds exhibited higher potent cytotoxicity to A549, HCT116 and MCF-7 cell lines. Conclusion: Especially, 3b, 3h, 3k, 3l, 3m, 3n, 3o, 3p and 3s simultaneously exhibited stronger inhibitory activity towards A549, HCT116 and MCF-7 cell lines than that of the reference drug cisplatin, which can be regarded as very promising metal-based lead compounds for anticancer agents.

Effects of a Heterogeneous Set of Xenobiotics on RNA Synthesis of Yeast Cells

Previously the toxicity of 45 heterogeneous environmental chemicals on growth and membrane functions in Saccharomyces cerevisiae and Chinese hamster ovary (CHO) cells (Cascorbi et al., 1993) was examined. In this study the inhibitory effects of the same set of chemicals on yeast RNA synthesis rate, measuring [2-(14)C]uracil uptake during cell proliferation are presented. The sensitivity of this test system was three to six times higher than that of the proliferation rate assay. In addition, the range of the EC20 values were similar to the range from the mammalian CHO cell proliferation test. The relatively good correlation with the yeast cell growth rate (r = 0.78, P = 0.0001) suggests that yeast RNA synthesis is a simple and rapid method of detecting a wide range of toxic compounds without the disadvantage of the insensitivity of the growth rate assay.

Copper-Catalyzed [4+2]-Cycloadditions of Isoxazoles with 2-Alkynylbenzaldehydes To Access Distinct alpha-Carbonylnaphthalene Derivatives: C(3,4)-versus C(4,5)-Regioselectivity at Isoxazoles

Cu(II)-catalyzed [4+2]-cycloadditions occur between Cu-benzopyryliums and substituted isoxazoles with the regioselectivity on the C(3,4)-carbons of isoxazoles. We postulate that a prior coordination of isoxazoles with Cu(OAc)2 increases the I-bond character of the C(3,4) carbons to become an effective 2I-donor. In this reaction sequence, 3,5-disubstituted isoxazoles yield alpha,I-dicarbonylnaphthalenes whereas, 5-substituted isoxazoles deliver alpha,I-dicarbonyl-beta-aminonaphthalenes. For unsubstituted isoxazole, its cycloaddition chemoselectivity is switched to the C(4,5)-addition regioselectivity to yield alpha-carbonyl-I-cyanonaphthalene derivatives.

Synthetic and medicinal prospective of structurally modified curcumins

Curcumin, a natural yellow phenolic compound, is present in various types of herbs, particularly in Turmeric, Curcuma longa Linn. (Zingiberaceae family) rhizomes. Curcumin is a polyphenolic natural compound with diverse and attractive biological activities. In the last decade curcumine and its various synthetic analogues have been prepared and evaluated for various pharmacological activities that prove it as a lead molecule against several biological targets. It is a natural antioxidant and exhibited many pharmacological activities such as anti-inflammatory, anti-microbial, anticancer, anti-Alzheimer in both preclinical and clinical studies. Moreover, Curcumin and its analogues have anti-tubercular, cardioprotective, anti-diabetic, hepatoprotective, neuroprotective, nephroprotective, antirheumatic and anti-viral activities. The substitutions of 1,6-heptadiene linkage moiety via carbonyl group sustituion and addition of heterocyclic linker; isoxazole, 1H-pyrazole, cyclopentanone, piperidin-4-one, N-methylpiperidin-4-one enhance biological activities. The structure activity relationship of various curcumin analogues is studied for medicinal purposes and it reveals that monocarbonyl linkage analogues have anticancer properties. The current review gives an insight of the history, chemistry, analogues and most interesting in vitro and in vivo studies on the biological effects of Curcumin and its analogues.

Non-acidic 1,3,4-trisubstituted-pyrazole derivatives as lonazolac analogs with promising COX-2 selectivity, anti-inflammatory activity and gastric safety profile

Twelve new compounds of 1,3,4-trisubstituted-pyrazole derivatives possessing two cyclooxygenase-2 (COX-2) pharmacophoric moieties (SO2Me or/and SO2NH2) 11a-c, 12a-c, 13a-c and 14a-c were designed and synthesized to be evaluated for their COX inhibition, anti-inflammatory activity, ulcerogenic liability. All compounds were more selective for COX-2 isozyme and showed good in vivo anti-inflammatory activity. The bisaminosulphonyl derivatives (14a-c) were the most COX-2 selective compounds (S.I. = 9.87, 9.50 and 9.22 respectively) and showed good anti-inflammatory potency (ED50 = 15.06, 42.51 and 50.43 mumol/kg respectively) in comparison with celecoxib (COX-2 S.I. = 8.61, ED50 = 82.2 mumol/kg). Also, compounds 14a-c were less ulcerogenic (ulcer indexes = 2.72?3.72) than ibuprofen (ulcer index = 20.25) and comparable to celecoxib (ulcer index = 2.93). In addition, to explain the preferential (COX-2) inhibitory and selectivity, the designed compounds were subjected to molecular docking studies. It was found that compound 14c with the highest COX-2 activity and selectivity exhibited a binding pattern and interactions similar to that of celecoxib with formation of more hydrogen-bond features.

Biodiversity, isolation and genome analysis of sulfamethazine-degrading bacteria using high-throughput analysis

Sulfamethazine (SM2) is one of the sulfonamide antibiotics that is frequently detected in aquatic environment. Given the complex structure of SM2 and its potential threat to the environment, it is necessary to determine the degradation behavior of high-concentration SM2. The mechanisms of community structure and diversity of activated sludge were analyzed. A novel SM2-degrading strain YL1 was isolated which can degrade SM2 with high concentration of 100?mg?L?1. Strain YL1 was identified as Paenarthrobacter ureafaciens and there was also a significant increase in the genus during acclimation. Additional SM2 metabolic mechanisms and genomic information of YL1 were analyzed for further research. The succession of the community structure also investigated the effect of SM2 on the activated sludge. This result not only advances the current understanding of microbial ecology in activated sludge, but also has practical implications for the design and operation of the environmental bioprocesses for treatment of antimicrobial-bearing waste streams.
