Squalamine, an endogenous molecule found in the liver and other tissues of Squalus acanthias, has antibiotic properties causes changes endothelial cell shape. The latter suggested that its potential targets might include transport proteins control volume or effect purified squalamine was examined on cloned Na+/H+ exchanger isoforms NHE1, NHE2, NHE3 stably transfected PS120 fibroblasts. Squalamine (1-h pretreatment) decreased maximal velocity rabbit a concentration-dependent manner (13, 47,...

The incidence of pyrimidine dimer formation and the kinetics DNA repair in African green monkey kidney CV-l cells after ultraviolet (UV) irradiation were studied by measuring survival, T4 endonuclease V-sensitive sites, fraction dimers acid-insoluble as determined thin layer chromatography (TLC), replication.CV-1 exhibit a survival curve with extrapolation number n -7.8 Do = 2.5 J/m2.Pyrimidine lost from acid- insoluble more slowly than endonuclease-sensitive sites or new bases incorporated...

Purpose To determine if systemically administered squalamine lactate, a novel aminosterol with antineoplastic and antiangiogenic activity, inhibits the development of experimental choroidal neovascularization membranes (CNVMs) induced by laser trauma in rat model. Methods Twenty anesthetized male Brown-Norway rats received series 8 krypton red lesions per eye (647 nm, 0.05 second, 50 μm, 150 mW). One half animals an intraperitoneal injection other one 5% dextrose water, all performed masked...

Purpose To investigate the effect of squalamine, an antiangiogenic aminosterol, in experimental model iris neovascularization. Methods Iris neovascularization was created cynomolgus monkeys by occluding retinal veins with argon laser and inducing persistent hypotony a central corneal suture. Twenty-four eyes were treated three groups. In Group 1, four injected intravitreally 3 μg/0.1 mL squalamine balanced saline solution (controls) immediately after vein occlusion (day 1); injections...

Purpose: To examine the pooled per-protocol ocular end points from two conjunctival allergen challenge (CAC) clinical trials of dual-action antihistamine bepotastine besilate ophthalmic solution (BBOS) 1.5%. Methods: Two Phase III, placebo-controlled, double-masked, randomized were conducted at a total six separate centers using CAC model allergic conjunctivitis. The same study design was employed for both trials, with subjects randomly assigned to either BBOS 1.5% (n=78) or placebo (n=79)...

This clinical trial evaluated the safety and effectiveness of bepotastine besilate ophthalmic solutions 1.0% 1.5% compared with placebo for treatment ocular itching conjunctival hyperemia (redness) using allergen challenge (CAC) model allergic conjunctivitis when dosed 16 h before a CAC test.Subjects history were assigned to receive or solution in single-center, randomized, placebo-controlled trial. Eligible subjects (n=107) aged 10 years older who had reproducible positive reaction enrolled...

Allergic conjunctivitis (AC) affects an estimated 20% of the population in Western world, with a large fraction suffering due to seasonal or perennial allergen exposures. Bepotastine besilate ophthalmic solution (BBOS) 1.5%, dual-acting histamine (H(1)) receptor antagonist and mast cell stabilizer, is indicated for itching associated AC. This study was designed evaluate efficacy safety BBOS 1.5% reducing ocular AC subjects enrolled natural exposure trial. Eligible multicenter, double-masked,...
