Imidazoline-1 Receptor Ligands as apoptotic agents: Pharmacophore Modeling and Virtual Docking study.

In this study we examined apoptotic activity of rilmenidine (potent I1-IR agonist), moxonidine (moderate I1-IR agonist), and efaroxan (I1-IR partial agonist) on cancer cell line (K562) expressing Nischarin. The Nischarine domains mapping was performed by use of the Informational Spectrum Method. (ISM). The 3D-Quantitative Structure-Activity Relationship (3D-QSAR) and virtual docking studies of 29 I1-IR ligands (agonists, partial agonists, and antagonists) were carried out on I1-IR receptors binding affinities. The 3D-QSAR study defined 3D-pharmacophore models for I1-IR agonistic and I1-IR antagonistic activity and created regression model for prediction of I1-IR activity of novel compounds. The 3D-QSAR models were applied for design and evaluation of novel I1-IR agonists and I1-IR antagonists. The most promising I1-IR ligands with enhanced activities than parent compounds were proposed for synthesis. The results of 3D-QSAR, ISM, and virtual docking studies were in perfect agreement and allowed precise definition of binding mode of I1-IR agonists (Arg 758, Arg 866, Val 981, and Glu 1057) and significantly different binding modes of I1-IR antagonists or partial I1-IR agonists.  The performed theoretical study provides reliable system for evaluation of I1-IR agonistic and I1-IR antagonistic activity of novel I1-IR ligands, as drug candidates with anticancer activities.

Conclusion: the therapeutic effect of small molecule targeting drug apatinib on gastric cancer is better than that of other drugs, whether in therapeutic effect, drug resistance, adverse reactions or infection control. This study has important reference significance for the follow-up treatment of apatinib and cancer.

AbstractIntroductionThe present study aimed to indirectly compare apalutamide and enzalutamide with respect to tolerability and health-related quality of life (HRQoL) among men with non-metastatic castration-resistant prostate cancer (nmCRPC).MethodsPatient-level data from the SPARTAN study [apalutamide  + androgen deprivation therapy (ADT) versus placebo + ADT] and aggregate published data from the PROSPER study (enzalutamide + ADT versus placebo + ADT) were used. Anchored matching-adjusted indirect comparison (MAIC) was conducted by weighting patients’ baselin...

[Daily Maverick] In the shadow of HIV many things are hidden. Do a quick Google search ('in the shadow of HIV') and a torrent of disease and social ills will blast across your browser. You'll find gender-based violence and stigma, sugar-daddies, obesity and hypertension, patriarchy, cancer and diabetes, denial, guilt, and the opioid crisis. Also hiding, deep in the shadows, are adolescent boys and young men.

Publication date: Available online 3 December 2019Source: Pharmacological ResearchAuthor(s): Carlo Fumagalli, Niccolò Maurizi, Niccolò Marchionni, Diego FornasariAbstractThe pharmacological class of β-blockers includes a plea of molecules with largely different pharmacokinetic and pharmacodynamic characteristics with a protective effect that may span far beyond the cardiovascular system. Although all these compounds share the pharmacological blockade of the adrenergic receptors, each of them is characterized by specific pharmacological properties, including selectivity of action depending on the adrenerg...

CONCLUSIONS: Apatinib can improve the disease control rate of recurrent and metastatic cervical cancer when chemotherapy has failed, and the treatment is well tolerated. This represents that apatinib may be a new treatment option for metastatic cervical cancer patients. PMID: 31788992 [PubMed - as supplied by publisher]

Drinking alcohol causes damage to your health in both the short term and long term, even for moderate drinkers. For individuals who suffer from addiction to alcohol and frequently drink in excess, these risks become higher. Knowing the risks of drinking alcohol is important to help avoid drinking to excess and reduce the likelihood of these risks. Short-Term Risks of Drinking Alcohol There are many short-term risks that occur when drinking alcohol. These risks can happen to anyone, including individuals suffering from alcohol use disorder, or individuals who are drinking for the very first time. Injuries When you drink al...

Abstract With the onset of a metabolic syndrome epidemic and the increasing life expectancy, erectile dysfunction (ED) has become a more common condition. As incidence and prevalence increase, the medical field is focused on providing more appropriate therapies. It is common knowledge that ED is a chronic condition that is also associated with a myriad of other disorders. Conditions such as aging, diabetes mellitus, hypertension, obesity, prostatic hypertrophy, and prostate cancer, among others, have a direct implication on the onset and progression of ED. Characterization and recognition of risk factors may help ...
