Journal: In silico interactions of statins with cell death-inducing DNA fragmentation factor-like effector A (CIDEA). (Pubmed Central) - Aug 4, 2021 The docking results indicated that atorvastatin and rosuvastatin showed the best interaction energy (-8.51 and -8.04 kcal/mol, respectively) followed by fluvastatin (-7.39), pitavastatin (-6.5), lovastatin (-6.23), pravastatin (-6.04) and simvastatin (-5.29)...Since two arginine residues -ARG19 and ARG22-were identified to be common for the interaction with CIDEA, a single-point mutation was induced in these residues to determine whether they are important for binding interaction. Mutation of these two residues seems to affect mostly the interaction of atorvastatin with CIDEA, suggesting that they are important for the binding and therefore indicate another possible metabolic mechanism of the pleiotropic effects of this statin.

Journal: Comparison of Transcriptomic Profiles of MiaPaCa-2 Pancreatic Cancer Cells Treated with Different Statins. (Pubmed Central) - Jul 31, 2021 However, their inhibitory action also causes depletion of downstream intermediates of the pathway, resulting in the pleiotropic effects of statins, including the beneficial impact in the treatment of cancer. In our study, we compared the effect of all eight existing statins on the expression of genes, the products of which are implicated in cancer inhibition and suggested the molecular mechanisms of their action in epigenetic and posttranslational regulation, and in cell-cycle arrest, death, migration, or invasion of the cancer cells.

Biomarker, Journal: Pitavastatin prevents ovariectomy-induced osteoporosis by regulating osteoclastic resorption and osteoblastic formation. (Pubmed Central) - Jul 30, 2021 Furthermore, we evaluated the therapeutic potential of pitavastatin in ovariectomy-induced systematic bone loss based on micro-computed tomography and histological analysis of femurs. Our findings demonstrated a new function and mechanism for pitavastatin in bone remodeling, indicating its potential as a therapeutic candidate in treating osteoporosis by inhibiting osteoclastic resorption and promoting osteoblastic formation.

Journal: Acute Statin Administration Reduces Levels of Steroid Hormone Precursors. (Pubmed Central) - Jul 29, 2021 Fourteen subjects not taking statins were administered a single oral dose (2 mg) of pitavastatin...A parallel study in mice entailed the administration of atorvastatin (10 mg/kg) via orogastric delivery for three consecutive days...We conclude that acute dysregulation of the production of certain glucocorticoid precursor molecules was observed after a single treatment with a lipophilic statin drug. This may be of clinical relevance for individuals with underlying or subclinical adrenal insufficiency.

Review, Journal: Diabetogenic effects of cardioprotective drugs. (Pubmed Central) - Jul 11, 2021 Dihydropyridine calcium channel blockers, low dose diuretics, vasodilating beta blockers, alfa-blockers and pitavastatin have little or no effect on glycemic control. Blockers of the renin-angiotensin-aldosterone system, colesevelam, ranolazine and verapamil through slowing breakdown of bradykinin, vasodilation, increasing cholecystokinin levels, blocking sodium channels, and decreasing beta cell apoptosis may improve glycemic control and avoid the development of diabetes.

Journal, PARP Biomarker: Pitavastatin and metformin synergistically activate apoptosis and autophagy in pancreatic cancer cells. (Pubmed Central) - Jul 7, 2021 These findings clearly indicated that metformin plus pitavastatin had a synergistic anticancer effect on pancreatic cancer cells, potentially caused due to the activation of AMPK and inhibition of PI3K/mTOR signaling. Altogether, our results provide that use of metformin plus pitavastatin maybe serve as a chemotherapeutic agent for human pancreatic cancer in future.

(Pubmed Central) - Jun 26, 2021 Suboptimal management of DDIs with statin underdosing was observed in 29% of prescriptions. Integrase inhibitor-based regimens and/or treatment with rosuvastatin or atorvastatin should be favoured in patients with refractory dyslipidaemia.

Because of the good safety profile and availability for both adult and pediatric uses, consideration should be given to repurposing the fast-acting pitavastatin for the treatment of PAM.

Journal: Evaluation of hepatic uptake of OATP1B substrates by short term-cultured plated human hepatocytes: Comparison with isolated suspended hepatocytes. (Pubmed Central) - Jun 22, 2021 For pravastatin and dehydropravastatin, hydrophilic compounds with low uptake/cellular binding, their PS and C/M ratio in PHH were 1.8- to 3.2-fold lower than those in SHH...The C/M ratios obtained using PHH were stable over an extended time, making PHH suitable to estimate the C/M ratios and hepatocyte-to-medium unbound concentration ratios (K). In conclusion, PHH is useful in evaluating hepatic uptake/efflux clearances and K of OATP1B substrates in a high-throughput manner, however, a caution is warranted for hydrophilic drugs with low uptake/cellular binding.

Review, Journal: Hydrophilic or Lipophilic Statins? (Pubmed Central) - Jun 8, 2021 The predominantly lipophilic statins (simvastatin, fluvastatin, pitavastatin, lovastatin and atorvastatin) can easily enter cells, whereas hydrophilic statins (rosuvastatin and pravastatin) present greater hepatoselectivity...Furthermore, adverse events with statin therapy may also be related to their solubility profile. Thus, the aim of the present review was to collect clinical evidence on possible differences in cardiovascular outcomes among statins when their solubility profile is considered, and how this may also be related to the occurrence of statin-related adverse effects.

Review, Journal: Potential Alteration of Statin-Related Pharmacological Features in Diabetes Mellitus. (Pubmed Central) - May 26, 2021 Plasma and serum concentrations of statins were accompanied by alteration in cellular activities including oxidative stress, Akt inhibition, and endothelial nitric oxide synthase (eNOS) and phosphorylation that were reflected in changes in the adverse drug reaction profile of the differing statins. Given that dyslipidemia frequently accompanies diabetes and statin therapy is common, more clinical studies are needed regarding the effects of diabetes on the effectiveness of these drugs.

Therefore, DDI data from healthy volunteers may represent a worst-case scenario for clinically de-risking P-gp and BCRP substrates in the setting of RI.

Journal: Pitavastatin induces apoptosis in oral squamous cell carcinoma through activation of FOXO3a.

Therefore, these findings might help to elucidate the underlying mechanism of the anticancer effects of pitavastatin on OSCC.
