< GPCR News < GPCRs in Oncology and Immunology In Silico Design of Novel RGS2-Galpha-q Interaction Inhibitors We sought to develop RGS2 inhibitors as potential chemotherapeutic agents utilizing structure-based drug hits to RGS2 as well as other RGS structures was used to screen the hits for potent and selective RGS2 inhibitors This is the first group of RGS2 inhibitors identified by structure-based approaches and that show anticancer These results highlight the potential RGS2 inhibitors have to be a new class of chemotherapeutic agents

Here, based on strong rationales, we studied the capacity of LP2 to inhibit the growth of patient-derived Kinome analyses and validation of elected kinase inhibition indicated that LP2-mediated AT 2 R stimulation inhibited PI3K/AKT/mTOR which resulted in apoptosis via CDKs. LP2 acted synergistically with 5-FU and the EGFR inhibitor erlotinib. together with its excellent specificity, safety and stability, warrant further evaluation of LP2's inhibitory

interrogate the role of GPR68 specifically in GBM cells using a novel highly specific small molecule inhibitor To determine GPR68 inhibition's mechanism of cell death we use DAVID pathway analysis of RNAseq. Using our small molecule inhibitor OGM and genetic means, we show that blocking GPR68 signaling results Importantly, OGM was not-acutely toxic to zebrafish and its inhibitory effects were found to spare non-malignant In this context, GPR68 suppresses ATF4, inhibition of GPR68 increases expression of ATF4 which leads

Stimulation of ectopically expressed muscarinic receptors induces IFN-γ but suppresses IL-2 production by inhibiting both muscarinic receptors plus the TCR even led to reduced IL-2 expression, suggesting a selective inhibitory This may explain the inhibitory impact on IL-2 production in hM3Dq/β1T cells. Moreover, an inhibitor of PI3K reduced IL-2 production in TCR-stimulated hM3Dq/β1 CD4 T cells, suggesting

Pharmacological inhibition of the lipid synthesis pathway by statins is a therapeutic approach to control manner, we investigated the molecular reasoning for this differential inhibition. prenylation of carboxy-terminus (Ct) mutated Gγ in cells exposed to Fluvastatin and prenyl transferase inhibitors Our results may also provide molecular reasoning for repurposing statins as Ras oncogene inhibitors and the failure of using prenyltransferase inhibitors in cancer treatment."

Crucially, SFKs promoted YAP nuclear localization and phosphorylation at Tyr357, as shown by using the SFK inhibitors dasatinib, saracatinib, the preferential YES1 inhibitor CH6953755, siRNA-mediated knockdown of YES1, Surprisingly, our results also demonstrate that exposure to SFK inhibitors, including dasatinib or knockdown Dasatinib-induced ERK activation was completely abolished by exposure to the FDA-approved MEK inhibitor rationale for considering a combination(s) of FDA-approved SFK (dasatinib) and MEK (e.g., trametinib) inhibitors

Immunology Spliceosome mutations are associated with clinical response in a phase 1b/2 study of the PLK1 inhibitor A phase 1b trial of the PLK1 inhibitor onvansertib (ONV) combined with decitabine (DAC) demonstrated PLK1 inhibition with ONV in combination with DAC could be a potential therapy in R/R AML patients, particularly

GRK2 inhibitors like paroxetine restore functions. Actin polymerization, CTX, bacterial phagocytosis and killing were also rescued therefore by the HDAC inhibitor Either GRK2 or HDAC inhibition prevented loss of mouse lung bacterial clearance, but only the combination Simultaneous GRK2/HDAC inhibition rescues susceptibility to infection after tissue injury.

Mechanistic studies revealed that 8GL treatment inhibits the activation of the mammalian target of rapamycin We further showed that the combination of 8GL and an mTOR inhibitor synergistically elicited AML cell Importantly, 8GL alone or in combination with an mTOR inhibitor remarkably impaired tumor growth and

Synergistic effects on calcium flux and cell migration are inhibited by the Gαi inhibitor pertussis toxin and the Gαq inhibitor YM254890, suggesting that the Gαi and Gαq pathways are involved in the synergy

chemokine ligands, activators and antagonists recognize hCCR3, and quantitative measurements of hCCR3 inhibition The study results indicate chemokines interact with hCCR3 at low concentrations, and reversible hCCR3 inhibitors solely inhibit hCCR3, not CCLs.
