A novel receptor cross-talk between the ATP receptor P2Y2 and formyl peptide receptors reactivates desensitized neutrophils to produce superoxide

Neutrophils express several G-protein coupled receptors (GPCRs) and they cross regulate each other. We described a novel cross-talk mechanism in neutrophils, by which signals generated by the receptor for ATP (P2Y2) reactivate desensitized formyl peptide receptors (FPRs) so that these ligand-bound inactive FPRs resume signaling. At the signaling level, the cross-talk was unidirectional, i.e., P2Y2 ligation reactivated FPR, but not vice versa and was sensitive to the phosphatase inhibitor calyculinA. Further, we show that the cross talk between P2Y2 and FPR bypassed cytosolic Ca2+ transients and did not rely on the actin cytoskeleton. In summary, our data demonstrate a novel cross-talk mechanism that results in reactivation of desensitized FPRs and, an amplification of the neutrophil response to ATP.

Identification and preclinical characterization of a novel and potent poly?(ADP-ribose) polymerase (PARP) inhibitor ZYTP1

Purpose: Poly(ADP-ribose) polymerase-1 (PARP-1) is a nuclear enzyme involved in the detection and repair of DNA damage. Studies have shown that inhibition of PARP and Tankyrase (TNKS) has significant antitumor effect in several types of cancers including BRCA-negative breast cancers. Methods: Identification of ZYTP1, a novel PARP inhibitor, through a battery of in vitro assays and in vivo studies. PARP and TNKS inhibitory activity of ZYTP1 was assessed in cell-free kinase assay. In vitro cell killing potency of ZYTP1 was tested in a panel of cell lines including BRCA-negative cells. ZYTP1 was also tested in xenograft models in combination with temozolomide (TMZ). The pharmacokinetic profile of ZYTP1 was determined in rodent and non-rodent preclinical species. Safety of ZYTP1 was assessed in Wistar rats and Beagle dogs upon repeated dosing. Results: ZYTP1 inhibited PARP1, PARP2, Tankyrase-1 and Tankyrase-2 with IC50 of 5.4, 0.7, 133.3 and 289.8?nM, respectively, and additionally trapped PARP1 onto damaged DNA. It also potentiated MMS-mediated killing of different cancer cell lines. Compound demonstrated good Caco-2 cell permeability. The oral bioavailability of ZYTP1 in mice, rats and dogs ranged between 40 and 79% and demonstrated efficacy in colon cancer xenograft model at a dose of 1?10?mg/kg in combination with TMZ. In a 28-day repeat dosing, oral toxicity study in rats, it was found to show > 10¡Á safety margin. Conclusions: ZYTP1 is a novel PARP inhibitor that showed potential for development as a treatment for various solid tumors.

Anticancer activity assessment of two novel binuclear platinum (II) complexes

In the current study, two binuclear Pt (II) complexes, containing cis, cis-[Me2Pt (mu-NN) (mu-dppm) PtMe2] (1), and cis,cis-[Me2Pt(mu-NN)(mu dppm) Pt((CH2)4)] (2) in which NN = phthalazine and dppm = bis (diphenylphosphino) methane were evaluated for their anticancer activities and DNA/purine nucleotide binding properties. These Pt (II) complexes, with the non-classical structures, demonstrated a significant anticancer activity against Jurkat and MCF-7 cancer cell lines. The results of ethidium bromide/acridine orange staining and Caspase-III activity suggest that these complexes were capable to stimulate an apoptotic mechanism of cell death in the cancer cells. Using different biophysical techniques and docking simulation analysis, we indicated that these complexes were also capable to interact efficiently with DNA via a non-intercalative mechanism. According to our results, substitution of cyclopentane (in complex 2) with two methyl groups (in complex 1) results in significant improvement of the complex ability to interact with DNA and subsequently to induce the anticancer activity. Overall, these binuclear Pt (II) complexes are promising group of the non-classical potential anticancer agents which can be considered as molecular templates in designing of highly efficient platinum anticancer drugs.

An organocatalytic enantioselective direct alpha-heteroarylation of aldehydes with isoquinoline: N -oxides

A new protocol for the enantioselective direct alpha-heteroarylation of aldehydes with isoquinoline N-oxides, via chiral enamine catalysis, has been successfully developed. High enantiomeric excesses and moderate to good yields were achieved for a variety of alpha-heteroarylated aldehydes.

Note that a catalyst decreases the activation energy for both the forward and the reverse reactions and hence accelerates both the forward and the reverse reactions.Computed Properties of C8H6N2, you can also check out more blogs about253-52-1

Functional characteristics of circulating granulocytes in severe congenital neutropenia caused by ELANE mutations

Background: Neutrophils and eosinophils are multifunctional granulocytes derived from common myelocytic-committed progenitor cells. Severe congenital neutropenia 1 (SCN1) caused by ELANE mutations is a rare disease characterized by very low numbers of circulating neutrophils. Little is known about the functional characteristics of the SCN1 granulocytes, except that eosinophilia has been noticed in both bone marrow and peripheral blood. In this study, we profiled the number and function of granulocytes in patients suffering from SCN1. Methods: Nine patients diagnosed with SCN1 were enrolled in this study and absolute counts of eosinophils and neutrophils from bone marrow aspirates and peripheral blood samples were analysed. In addition, Ficoll-Paque enriched granulocytes from patients and healthy controls were analysed for specific eosinophil and neutrophil markers using flow cytometry and for NADPH-oxidase activity-profile by chemiluminescence. Results: Our data demonstrate a skewed granulocyte population in SCN1 patients dominated by eosinophils in both bone marrow and peripheral blood. The latter was detected only by blood smear examination, but not by automated blood analysers. Furthermore, we show that the SCN1 eosinophils exerted normal production of reactive oxygen species generated by the NADPH-oxidase, however the response was profoundly different from that of healthy control neutrophils. Conclusions: SCN1 patients with ELANE mutations suffer from neutropenia yet display eosinophilia in the bone marrow and blood, as revealed by smear examination but not by automatic blood analysers. The SCN1 eosinophils are functionally normal regarding production of reactive oxygen species (ROS). However, the ROS profile produced by eosinophils differs drastically from that of neutrophils isolated from the same blood donor, implying that the eosinophilia in SCN1 cannot compensate for the loss of neutrophils regarding ROS-mediated functions.

Potassium Salt of Fullerenylpenta-N-Dihydroxytyrosine Effects on Type 2 Diabetes Mellitus Therapeutic Targets

Abstract: It was shown for the first time that pentaamino acid derivative of fullerene C60 (potassium salt of fullerenylpenta-N-dihydroxytyrosine) affects three targets of type 2 diabetes mellitus. It competitively inhibits the enzymes aldose reductase and sorbitol dehydrogenase and also has an antiglycation effect on bovine serum albumin. The inhibition constants for these enzymes were calculated.

Design, synthesis and anticancer activities of novel dual poly(ADP-ribose) polymerase-1/histone deacetylase-1 inhibitors

Currently, synergistic inhibition of poly(ADP-ribose) polymerase-1 (PARP-1) and histone deacetylases (HDACs) has been a potential effective strategy for cancer treatment. Herein, by combining critical pharmacophores in approved drugs olaparib and chidamide, a series of novel 2-fluoro-5-((4-oxo-3,4-dihydrophthalazin-1-yl)methyl)benzoic acid derivatives were designed and synthesized. All efforts led to a good dual PARP-1/HDAC-1 inhibitor, compound 4, with IC50 values of 4.2 and 340 nM against PARP-1 and HDAC-1, which were as potent as olaparib and chidamide respectively. The MTT assay further demonstrated that compound 4 had potent inhibitory activities against BRCA1/2-proficient K562 and MDA-MB-231 cells with GI50 values of 5.6 and 4.3 muM, respectively. Therefore, our results suggested that compound 4 could be a promising dual PARP-1/HDAC-1 inhibitor for further studies. In addition, a few excellent PARP-1 inhibitors such as 7?9 and HDAC-1 inhibitors such as 12 were serendipitously discovered, which also could be further studied in our next work.
