Adenosine kinase (AdK) inhibitors raise endogenous adenosine levels, particularly in disease states, and have potential for treatment of seizures, neurodegeneration, and inflammation. On the basis of the South (S) ribose conformation and mol. dynamics (MD) anal. of nucleoside inhibitors bound in AdK X-ray crystallog. structures, (S)- and North (N)-methanocarba (bicyclo[3.1.0]hexane) derivatives of known inhibitors were prepared and compared as human (h) AdK inhibitors. 5′-Hydroxy (I, MRS4202 (S); III, MRS4380 (N)) and 5′-deoxy II (MRS4203 (S)) analogs, containing 7- and N⁶-NH Ph groups in 7-deazaadenine, robustly inhibited AdK activity (IC₅₀ ∼ 100 nM), while the 5′-hydroxy derivative 30 lacking the Ph substituents was weak. Docking in the hAdK X-ray structure and MD simulation suggested a mode of binding similar to 5′-deoxy-5-iodotubercidin and other known inhibitors. Thus, a structure-based design approach for further potency enhancement is possible. The potent AdK inhibitors in this study are ready to be further tested in animal models of epilepsy.

Loss of haspin suppresses cancer cell proliferation by interfering with cell cycle progression at multiple stages was written by Wang, Peiling;Hua, Xiangmei;Sun, Yang;Li, Hongyu;Bryner, Yuge Han;Hsung, Richard P.;Dai, Jun. And the article was included in FASEB Journal in 2021.Related Products of 24386-93-4 The following contents are mentioned in the article:

Our recent studies have shown that haspin, a protein kinase imperative for mitosis, is engaged in the interphase progression of HeLa and U2OS cancer cells. In this investigation, we employed the Fucci reporter system and time-lapse imaging to examine the impact of haspin gene silencing on cell cycle progressions at a single-cell level. We found that the loss of haspin induced multiple cell cycle defects. Specifically, the S/G2 duration was greatly prolonged by haspin gene depletion or inhibition in synchronous HeLa cells. Haspin gene depletion in asynchronous HeLa and U2OS cells led to a similarly protracted S/G2 phase, followed by mitotic cell death or postmitotic G1 arrest. In addition, haspin deficiency resulted in robust induction of the p21CIP1/WAF1 checkpoint protein, a target of the p53 activation. Also, co-depleting haspin with either p21 or p53 could rescue U2OS cells from postmitotic G1 arrest and partially restore their proliferation. These results substantiate the haspin′s capacity to regulate interphase and mitotic progression, offering a broader antiproliferative potential of haspin loss in cancer cells. This study involved multiple reactions and reactants, such as (2R,3R,4S,5R)-2-(4-Amino-5-iodo-7H-pyrrolo[2,3-d]pyrimidin-7-yl)-5-(hydroxymethyl)tetrahydrofuran-3,4-diol (cas: 24386-93-4Related Products of 24386-93-4).

Tumor suppressor p53, which is activated by various stress and oncogene activation, is a target for anti-cancer drug development. In this study, by screening panels of protein kinase inhibitors and protein phosphatase inhibitors, we identified 5-Iodotubercidin as a strong p53 activator. 5-Iodotubercidin is purine derivative and is used as an inhibitor for various kinases including adenosine kinase. We found that 5-Iodotubercidin could cause DNA damage, verified by induction of DNA breaks and nuclear foci pos. for γH2AX and TopBP1, activation of Atm and Chk2, and S15 phosphorylation and up-regulation of p53. As such, 5-Iodotubercidin induces G2 cell cycle arrest in a p53-dependent manner. Itu also induces cell death in p53-dependent and -independent manners. DNA breaks were likely generated by incorporation of 5-Iodotubercidin metabolite into DNA. Moreover, 5-Iodotubercidin showed anti-tumor activity as it could reduce the tumor size in carcinoma xenograft mouse models in p53-dependent and -independent manners. These findings reveal 5-Iodotubercidin as a novel genotoxic drug that has chemotherapeutic potential.

Trypanosoma cruzi is the causative pathogen of Chagas disease and the main culprit for cardiac-related mortality in Latin-America triggered by an infective agent. Incapable of synthesizing purines de novo, this parasite depends on acquisition and processing of host-derived purines, making purine (nucleoside) analogs a potential source of antitrypanosomal agents. In this respect, hitherto 7-deazaadenosine (tubercidin) analogs attracted most attention. Here, we investigated analogs with an addnl. nitrogen (N1) removed. Structure-activity relationship investigation showed that C7 modification afforded analogs with potent antitrypanosomal activity. Halogens and small, linear carbon-based substituents were preferred. Compound 11 proved most potent in vitro, showed full suppression of parasitemia in a mouse model of acute infection, and elicited 100% animal survival after oral dosing at 25 mg/kg b.i.d. for 5 and 15 days. Cyclophosphamide-induced immunosuppression led to recrudescence. Washout experiments demonstrated a lack of complete clearance of infected cell cultures, potentially explaining the in vivo results.

Overexpression of CYP2E1 induces HepG2 cells death by the AMP kinase activator 5′-aminoimidazole-4-carboxamide-1-β-d-ribofuranoside (AICAR) was written by Zhuge, Jian. And the article was included in Cell Biology and Toxicology in 2009.Computed Properties of C11H13IN4O4 The following contents are mentioned in the article:

5′-Adenosine monophosphate (AMP)-activated protein kinase (AMPK) is a phylogenetically conserved serine/threonine protein kinase. AMPK may inhibit cell growth and proliferation and also regulates apoptosis. 5′-aminoimidazole-4-carboxamide-1-β-d-ribofuranoside (AICAR) is a cell-permeable AMPK activator. Activation of AMPK with AICAR has been shown to induce apoptosis of the rat hepatoma cell line FTO2B cells and almost completely inhibited HepG2 cells growth. In this study, a HepG2 cell line, which was transfected with a vector containing human CYP2E1 cDNA (E47 cells), was treated with AICAR. Cell proliferation was blocked, and apoptosis and necrosis were elevated as assessed by cellular morphol., DNA content assay, and lactate dehydrogenase leakage. AICAR treatment significantly increases CYP2E1 activity (20-fold) and expression (5.5-fold) in E47 cells. Iodotubericidin, which inhibits the conversion of AICAR to its activated form AICAR monophosphate, the antioxidants trolox and MnTMPyP, and 4-methylpyrazole, an inhibitor of CYP2E1, all can protect the E47 cells from AICAR-induced necrosis. Production of intracellular reactive oxygen species was increased by AICAR treatment in E47 cells. The cytotoxicity mechanism of AICAR in E47 cells is suggested to include AMPK activation, p53 phosphorylation, p21 expression, overexpression of CYP2E1, and intracellular ROS accumulation. This study involved multiple reactions and reactants, such as (2R,3R,4S,5R)-2-(4-Amino-5-iodo-7H-pyrrolo[2,3-d]pyrimidin-7-yl)-5-(hydroxymethyl)tetrahydrofuran-3,4-diol (cas: 24386-93-4Computed Properties of C11H13IN4O4).

Giardia lamblia is one of the most common eukaryotic pathogens and is classified by the CDC as a category B agent of bioterrorism. In a departure from more traditional research focused on specific pathways or mols., we have developed a high-throughput assay for screening libraries of small compounds for inhibitors and enhancers of trophozoite multiplication. Following a 24-h period of culture in 384-well plates in the presence of compounds, trophozoites were fixed, stained and enumerated. Quadruplicate screening of 1520 compounds from two libraries of known bioactives detected numerous inhibitory compounds Based on a stringent cut-off of 5 standard deviations from the plate mean, 50 compounds (3.3%) were inhibitory. The activity of 3 compounds was confirmed in conventional culture. Although not meeting the threshold, one compound (indirubin) was identified as an agonist of trophozoite proliferation. Demonstrating the potential of high-throughput screening for rapidly finding new compounds which perturb G. lamblia multiplication, most of the hits identified by high-throughput screening do not appear to have been tested previously for their ability to affect G. lamblia trophozoites. High-throughput screening of bioactive compounds will open new avenues to a system-wide anal. of pathways affecting G. lamblia proliferation, and eventually to other phases of the life cycle.

Inhibition of HDAC6 by tubastatin A disrupts mouse oocyte meiosis via regulating histone modifications and mRNA expression was written by Sui, Liyan;Huang, Rong;Yu, Hao;Zhang, Sheng;Li, Ziyi.

Histone deacetylase 6 (HDAC6) participates in mouse oocyte maturation by deacetylating α-tubulin. However, how HDAC6 expression is regulated in oocytes remains unknown. In the present study, we discovered that mouse oocytes had a high level of HDAC6 expression and a low level of DNA methylation status in their promoter region. Then, a selective HDAC6 inhibitor, tubastatin A (Tub-A) was chosen to investigate the role of HDAC6 in oocyte maturation. Our results revealed that inhibition of HDAC6 caused meiotic progression arrest, disturbed spindle/chromosome organization, and kinetochore-microtubule attachments without impairing spindle assembly checkpoint function. Moreover, inhibition of HDAC6 not only increased the acetylation of α-tubulin but also elevated the acetylation status of H4K16 and decreased the phosphorylation level of H3T3 and H3S10. Conversely, depressed H3T3 phosphorylation by its kinase inhibitor increased the acetylation level of H4K16. Finally, single cell RNA-seq anal. revealed that the cell cycle-related genes CCNB1, CDK2, SMAD3, YWHAZ and the methylation-related genes DNMT1 and DNMT3B were strongly repressed in Tub-A treated oocytes. Taken together, our results indicate that HDAC6 plays important roles in chromosome condensation and kinetochore function via regulating several key histone modifications and mRNA transcription during oocyte meiosis.

Efforts to construct therapeutically useful models of biol. systems require large and diverse sets of data on functional connections between their components. Here the authors show that cellular responses to combinations of chems. reveal how their biol. targets are connected. Simulations of pathways with pairs of inhibitors at varying doses predict distinct response surface shapes that are reproduced in a yeast experiment, with further support from a larger screen using human tumor cells. The response morphol. yields detailed connectivity constraints between nearby targets, and synergy profiles across many combinations show relatedness between targets in the whole network. Constraints from chem. combinations complement genetic studies, because they probe different cellular components and can be applied to disease models that are not amenable to mutagenesis. Chem. probes also offer increased flexibility, as they can be continuously dosed, temporally controlled, and readily combined. After extending this initial study to cover a wider range of combination effects and pathway topologies, chem. combinations may be used to refine network models or to identify novel targets. This response surface methodol. may even apply to non-biol. systems where responses to targeted perturbations can be measured.

A fundamental impediment to functional recovery from spinal cord injury (SCI) and traumatic brain injury is the lack of sufficient axonal regeneration in the adult central nervous system. There is thus a need to develop agents that can stimulate axon growth to re-establish severed connections. Given the critical role played by protein kinases in regulating axon growth and the potential for pharmacol. intervention, small mol. protein kinase inhibitors present a promising therapeutic strategy. Here, the authors report a robust cell-based phenotypic assay, utilizing primary rat hippocampal neurons, for identifying small mol. kinase inhibitors that promote neurite growth.

Structure and functional characterization of the atypical human kinase haspin was written by Eswaran, Jeyanthy;Patnaik, Debasis;Filippakopoulos, Panagis;Wang, Fangwei;Stein, Ross L.;Murray, James W.;Higgins, Jonathan M. G.;Knapp, Stefan. And the article was included in Proceedings of the National Academy of Sciences of the United States of America in 2009.Reference of 24386-93-4 The following contents are mentioned in the article:

Protein kinase haspin/Gsg2 plays an important role in mitosis, where it specifically phosphorylates Thr-3 in histone H3 (H3T3). Its protein sequence is only weakly homologous to other protein kinases and lacks the highly conserved motifs normally required for kinase activity. Here, the authors report crystal structures of human haspin in complex with ATP and the inhibitor, 5-iodotubercidin. These structures reveal a constitutively active kinase conformation, stabilized by haspin-specific inserts. Haspin also has a highly atypical activation segment well adapted for specific recognition of the basic histone tail. Despite the lack of a DFG motif, ATP binding to haspin was similar to that in classical kinases; however, the ATP y-phosphate formed H-bonds with the conserved catalytic loop residues, Asp-649 and His-651, and a H651A haspin mutant was inactive, suggesting a direct role for the catalytic loop in ATP recognition. Enzyme kinetic data showed that haspin phosphorylates substrate peptides through a rapid equilibrium random mechanism. A detailed anal. of histone modifications in the neighborhood of H3T3 revealed that increasing methylation at Lys-4 (H3K4) strongly decreased substrate recognition, suggesting a key role of H3K4 methylation in the regulation of haspin activity.
