BACKGROUND: Exposure to intermittent hypoxia (IH) may enhance cardiac function and protects heart against ischemia-reperfusion (I/R) injury. To elucidate the underlying mechanisms, we developed a cardioprotective IH model that was characterized at hemodynamic, biochemical and molecular levels. METHODS: Mice were exposed to 4 daily IH cycles (each composed of 2-min at 6-8% O2 followed by 3-min reoxygenation for 5 times) for 14 days, with normoxic mice as controls. Mice were then anesthetized and subdivided in various subgroups for analysis of contractility (pressure-volume loop), morphology, biochemistry or resistance to I/R (30-min occlusion of the left anterior descending coronary artery (LAD) followed by reperfusion and measurement of the area at risk and infarct size). In some mice, the phosphatidylinositide 3-kinase (PI3K) inhibitor wortmannin was administered (24 µg/kg ip) 15 min before LAD. RESULTS: We found that IH did not induce myocardial hypertrophy; rather both contractility and ...

The synthesis and antitumour and antibacterial activity of coumarin and chromone phosphorohydrazones have been reported. This study describes influence of phosphorohydrazones derivatives of coumarin and chromone on the polymerization and viscosity of fibrin. The fibrin polymerization assay was performed by the Shen and Lorand method and the clot viscosity was measured on the basis of Shen and Lorand and Marchi and coworkers methods. Among the eight compounds tested, one coumarin derivative and two chromone derivatives showed significant activity ...
Interleukin (IL)-23 and IL-12 are closely related in structure, and these cytokines regulate both innate and adaptive immunity. However, the precise signaling networks that regulate the production of each in Toxoplasma gondii-infected THP-1 monocytic cells, particularly the PI3K/AKT and MAPK signaling pathways, remain unknown. In the present study, T. gondii infection upregulated the expression of IL-23 and IL-12 in THP-1 cells, and both cytokines increased with parasite dose. IL-23 secretion was strongly inhibited by TLR2 monoclonal antibody (mAb) treatment in a dose-dependent manner and by TLR2 siRNA transfection, whereas IL-12 secretion was strongly inhibited by TLR4 mAb treatment dose-dependently and by TLR4 siRNA transfection. IL-23 production was dose-dependently inhibited by the PI3K inhibitors LY294002 and wortmannin, whereas IL-12 production increased dose-dependently. THP-1 cells exposed to live T. gondii tachyzoites underwent rapid p38 MAPK, ERK1/2 and JNK activation. IL-23 production ...

NU7441, also known as KU-57788, is a highly potent and selective DNA-PK inhibitor (IC50=14 nM), exhibiting ATP-competitive inhibition kinetics. NU7441 increased the cytotoxicity of ionizing radiation and etoposide in SW620, LoVo, and V3-YAC cells but not in V3 cells, confirming that potentiation was due to DNA-PK inhibition. NU7441 substantially retarded the repair of ionizing radiation-induced and etoposide-induced DSB.
Understanding of mechanisms of resistance to PI3K inhibitors is of paramount importance. PTEN is a major negative regulator of PI3K pathway.
Akt1通过抑制凋亡过程从而参与细胞存活途径。Akt1亦能诱导蛋白合成通路，故其在导致骨骼肌肥大及的一般组织生长的细胞通路中是一种重要信号蛋白。因其可以阻断凋亡并继而促进细胞存活，现已表明Akt1在多种肿瘤中起到主要作用。Akt（先亦被称为Akt1）首先是在转化逆转录病毒AKT8中被鉴定为癌基因的。 Akt2在胰岛素信号通路中是一重要的信号分子。需要其来诱导葡萄糖转运。在敲除Akt1但具正常Akt2的小鼠中，血糖稳态不受干扰，但动物体型会较小，这与Akt1在生长中起得作用是一致的。相反，Akt2缺失但具有正常Akt1的的小鼠生长略缺陷且表现出糖尿病表型（胰岛素抵抗），这从另一方面印证了Akt2对胰岛素受体信号通路更具特异性的这一设想。 Akt3似乎主要在脑中表达，但其作用仍未明晰。有报道显示Akt3缺失的小鼠脑部较小。 ...

A series of 7-hydroxy, 8-hydroxy and 7,8-dihydroxy synthetic chromone derivatives was evaluated for his or her DPPH free radical scavenging activities. Thirty-six synthetic chromone derivatives (indicated as compounds 1C36) were assessed for his or her antioxidant activities by DPPH radical scavenging assay. As demonstrated in Furniture 1 and ?and2,2, various chromones exhibited different degrees of activity, which range from EC50 = 2.58 to 182.77 M that are stronger than the popular organic antioxidants, e.g., luteolin and quercetin which possessed IC50 = 10.89 and 11.04 M,  respectively. Structure-radical scavenging activity romantic relationship demonstrated how the 7,8-dihydroxy-2-phenyl-3-benzoyl substituted compounds (compounds 29, 30 and 36) exhibited a strong antioxidant activity with low log EC50. This indicated that dihydroxy substitution (cathecol group) on ring A was LGD1069 essential for radical scavenging activity. The presence of benzoyl group at position 3 confers a high ...
Activation of the serine/threonine kinase Akt contributes to the formation, maintenance, and therapeutic resistance of cancer, which is driving development of compounds that inhibit Akt. Phosphatidylinositol ether lipid analogues (PIAs) are analogues of the products of PI3K that inhibit Akt activation, translocation, and the proliferation of a broad spectrum of cancer cell types. To gain insight into the mechanism of PIAs, time-dependent transcriptional profiling of 5 active PIAs and the PI3K inhibitor LY294002 (LY) was performed in NSCLC cells using high-density oligonucleotide arrays. Gene ontology analysis revealed genes involved in apoptosis, wounding response, and angiogenesis were upregulated by PIAs, while genes involved in DNA replication, repair and mitosis were suppressed. Genes that exhibited early differential expression were partitioned into 3 groups; those induced by PIAs only (DUSP1, KLF6, CENTD2, BHLHB2, PREX1), those commonly induced by PIAs and LY (TRIB1, KLF2, RHOB and ...
ZSTK474 is a novel orally applicable phosphoinositide 3-kinase-specific inhibitor that strongly inhibits cancer cell proliferation. Combination treatment using X-rays then ZSTK474 given orally for 8 days, starting 24h post-irradiation, significantly enhanced cell growth inhibition. The combined effect was also observed for clonogenic survival with continuous ZSTK474 treatment. Western blot analysis showed enhanced phosphorylation of Akt and GSK-3β by X-irradiation, whereas phosphorylation was inhibited by ZSTK474 treatment alone. Treatment with ZSTK474 after X-irradiation also inhibited phosphorylation, and remarkably inhibited xenograft tumor growth.

TY - JOUR. T1 - Structural Determinants of Isoform Selectivity in PI3K Inhibitors. AU - Miller, Michelle S.. AU - Thompson, Philip E.. AU - Gabelli, Sandra B. PY - 2019/2/26. Y1 - 2019/2/26. N2 - Phosphatidylinositol 3-kinases (PI3Ks) are important therapeutic targets for the treatment of cancer, thrombosis, and inflammatory and immune diseases. The four highly homologous Class I isoforms, PI3K, PI3K, PI3K and PI3K have unique, non-redundant physiological roles and as such, isoform selectivity has been a key consideration driving inhibitor design and development. In this review, we discuss the structural biology of PI3Ks and how our growing knowledge of structure has influenced the medicinal chemistry of PI3K inhibitors. We present an analysis of the available structure-selectivity-activity relationship data to highlight key insights into how the various regions of the PI3K binding site influence isoform selectivity. The picture that emerges is one that is far from simple and emphasizes the ...
This study found that compounds exhibiting antioxidant properties, i.e., NAC, PBN, and lipoic acid, prevent ANG II from activating the transcription factor NFAT3 in cardiomyocytes. Consistent with the hypothesis that oxidants mediate NFAT3 activation, we found that H2O2 induces activation of NFAT3 transcription factor in a narrow dose range (50-150 μM) within 1-8 h. A chemical inhibitor of ERKs, PD98059, inhibited H2O2 from activating NFAT3. In contrast, the PI3K inhibitor LY249002 and the p38 MAPK inhibitor SB202190 failed to show an inhibitory effect on H2O2-induced NFAT3 activation. A dominant negative form of c-Jun, TAM67, abolished NFAT3 activation. Because PD98059 inhibits the activation of AP-1 transcription factors by H2O2 (46), our data suggest a role of AP-1 downstream of ERKs in the H2O2-induced NFAT3 activation in cardiomyocytes.. Cooperation of NFATs with other families of transcription factors is an important character of NFATs in regulating gene expression. There is evidence that ...
