The lipophilic cationic compound quinacrine has been used as an antimalarial drug for over 75 years but its pharmacokinetic profile is limited. Here, we report on the pharmacokinetic properties of quinacrine in mice. Following an oral dose of 40 mg/kg/day for 30 days, quinacrine concentration in the brain of wild-type mice was maintained at a concentration of ~1 μM. As a substrate of the P-glycoprotein (P-gp) efflux transporter, quinacrine is actively exported from the brain, preventing its accumulation to levels that may show efficacy in some disease models. In the brains of P-gp-deficient Mdr10/0 mice, we found quinacrine reached concentrations of ~80 μM without any signs of acute toxicity. Additionally, we examined the distribution and metabolism of quinacrine in the wild-type and Mdr10/0 brains. In wild-type mice, the co-administration of cyclosporin A, a known P-gp inhibitor, resulted in a 6-fold increase in the accumulation of quinacrine in the brain. Our findings argue that the inhibition of the P-gp efflux transporter should improve the poor pharmacokinetic properties of quinacrine in the CNS. © 2012 Ahn et al. Source

The suitability of the ovine forestomach matrix (OFM) for the treatment of recalcitrant wounds was evaluated in 19 patients. At 12 weeks, 50% of wounds had closed, and the average reduction in surface area was 73.4%. Promising outcomes of this initial series support the clinical consideration of OFM.

The present invention pertains to the development of Extracellular Matrix (ECM) scaffolds derived from the forestomach of a ruminant. Such scaffolds are useful in many clinical and therapeutic applications, including wound repair, tissue regeneration, and breast reconstruction. In addition, the present invention features methods of isolating ECM scaffolds from mammalian organs, including but not limited to the ruminant forestomach. The invention further features laminated ECM scaffolds containing a polymer positioned between individual ECM sheets. The polymer may optionally contain bioactive molecules to enhance the functionality of the scaffold.
