  To date, PCSK9 has been scantly investigated in cancer. The question that needs to be discussed is "How does PCSK9 act in cancer pathophysiology and what are the risks or benefits associated to its inhibition?". We reviewed the available publications highlighting the contribution of this proprotein convertase in pathways related to cancer, with focus on the potential implications of its long-term pharmacological inhibition in cancer therapy.

Because of that many strategies are being developed in order to combat the resistance of microorganisms to drugs, in recent times, chalcones have been studied for this purpose. Chalcones are known as α, β-unsaturated ketones, characterized by having the presence of two aromatic rings that are joined by a three-carbon chain, they are a class of compounds considered an exceptional model due to chemical simplicity and a wide variety of biological activities, which include anticancer, anti-inflammatory, antioxidants, antimicrobials, anti-tuberculosis, anti-HIV, antimalarial, anti-allergic, antifungal, antibacterial, and antileishmanial. The objective of this work was evaluate the antibacterial and antibiotic modifying activity of chalcone (E)-1-(2-hydroxyphenyl)-3-(2,4-dimethoxy-3-methylphenyl)prop-2-en-1-one against the bacteria Staphylococcus aureus carrying a NorA and MepA efflux pump. The results showed that chalcone was able to synergistically modulate the action of Norfloxacin and Ethidium Bromide against the bacteria Staphylococcus aureus 1199B and K2068, respectively. The theoretical physicochemical and pharmacokinetic properties of chalcone showed that the chalcone did not present a severe risk of toxicity such as genetic mutation or cardiotoxicity, constituting a good pharmacological active ingredient.Danhong injection (DHI) is a compound Chinese medicine widely used in China for treatment of ischemic cardio-cerebrovascular diseases. However, limited data are available regarding the protective effect of DHI on the ischemic penumbra in ischemic stroke. This study aimed to investigate the effect of intravenous DHI on neuronal injure in the ischemic penumbra after cerebral ischemia/reperfusion (CI/R), focusing especially on the involvement of intracellular energy metabolism coupling. Male Sprague-Dawley rats were subjected to right middle cerebral artery occlusion for 60 min followed by reperfusion with or without intravenous DHI (0.5, 1.0, or 2.0 mL/kg) once daily for 7 days. Post-treatment with DHI ameliorated neurological defects, diminished cerebral infarction, alleviated cerebral edema, improved microcirculatory perfusion after 7days of reperfusion, and inhibited apoptosis and enhanced neuronal survival in the ischemic penumbra. In addition, DHI significantly ameliorated oxidative stress, reduced DNA damage, and inhibited the activation of PARP1/AIF pathway, thereby restoring cytoplasmic glycolytic activity. Furthermore, this drug increased PDH activity by inhibiting the HIF1α/PDK1 signaling pathway, thus eliminating the inhibitory effect of CI/R on mitochondrial metabolism. The results of this study suggest that DHI can alleviate cerebral edema after CI/R and rescue the ischemic penumbra, and these protective effects are due to the regulation of intracellular energy metabolic coupling.Traumatic brain injury (TBI) is characterized by a complex network of signals mediating inflammatory, proliferative and apoptotic processes during its acute and chronic phases. Current therapies mitigate damage and are mainly for palliative care and there are currently no effective therapies for secondary damage. This suggests a need to discover a compound with a greater spectrum of action that can control various pathological aspects of TBI. Here we used a network pharmacology approach to explore the benefits of tibolone, an estrogen and androgen receptor agonist with broader actions in cells, as a possible repurposing drug for TBI therapy. Using different databases we retrieved the targets significantly associated to TBI and tibolone, obtaining 2700 and 652, respectively. The top 10 GO enriched terms were mostly related to cell proliferation, apoptosis and inflammation. Following protein-protein functional analysis, the top connected proteins were related to kinase activity (MAPK1/14/3, AKT1 PIK3R1), apoptosis (TP53, CASP3), growth factors (EGFR), estrogen signalling (ESR1) and inflammation (IL6, TNF), with IL6 as an important signalling hub belonging to the top GO categories. Thus, we identified IL6 as a cellular node which we then validated using molecular mechanics-generalized born surface area (MMGBSA) and docking to explore which tibolone metabolite might interact with this protein. Both 3α and 3β-OH tibolone seemed to bind better to IL6 at important sites responsible for its binding to IL6R. In conclusion, our study demonstrates key hubs involved in TBI pathology which indicates IL6 as a target molecule of tibolone as drug repurposing for TBI therapy.
  Polycythemia vera (PV) is a refractory hematological disease that lack of effective therapy. Chinese traditional medicine Longchai Jiangxue formula (LCJX) has showed the powerful effects on PV. However, the active ingredients and mechanisms of this formula have not been elucidated. We explored the active ingredients and mechanisms of LCJX for treating PV.
 
  The chemical constituents of LCJX were qualitatively analyzed by UPLC/Q-TOF-MS/MS. On this basis, the TCMSP, ETCM, PubChem BioAssay and ChEMBL databases were searched to predict the potential targets of chemical components of LCJX.  https://www.selleckchem.com/products/c188-9.html  Then Genecards, GEO, DisGeNET, and OMIM databases were used to retrieve data of targets related to PV. Drug-disease-target network and protein-protein-interaction (PPI) network were built. Gene Ontology (GO) and Kyoto Encyclopedia of Genes and Genomes (KEGG) enrichment analysis were performed. Finally, Molecular docking, CCK-8 assay, Annexin V-FITC/PI staining and western blot were processed so as to screen the active components related to PV and elucidate its mechanisms.
