Description: METHODS FOR INCREASING NITRIC OXIDE SYNTHASE ACTIVITY This invention relates to methods of using substituted indole compounds to increase or maintain nitric oxide synthesis in a mammal, preferably in a human. More particularly, this invention relates to methods of using substituted indole compounds to increase or maintain nitric oxide synthase activity and the output of nitric oxide from endothelial cells. Background of the Invention Nitric oxide (NO) acts as a regulator in the cardiovascular, intestinal, central nervous, and immune systems. Biologically, it is involved in a variety of actions including neurotransmission, vasodilation, cytotoxicity of macrophages and inhibition of platelet aggregation. It is synthesized from L-arginine by enzymes known as NO synthase (NOS). The calcium dependent form of NOS ' produced in vascular endothelial cells, referred to as eNOS, has been indicated to be regulated through concentrations of estrogen. Estrogen has been indicated in the up-regulation of eNOS m-RNA production and the subsequent endothelial cell synthesis of eNOS. This increased eNOS level allows the endothelial cells to produce more NO in response to relevant vascular system stimuli. In the vascular system, nitric oxide acts to inhibit platelet aggregation, inflammatory cell adhesion, as well as smooth muscle cell proliferation. It is also a regulator of smooth muscle and vascular tone, playing an essential role in regulation of blood pressure. It is also indicated in preventing oxidative modification of low- density lipoprotein (LDL), which contributes to atherosclerosis, particularly in its oxidized form. From a physiological and pharmacologic perspective, increasing vascular levels of NO is beneficial in many pathologic conditions, including diabetes, stroke, atherosclerosis, and hypertension.

Example 1. TSE-424 Acetate - Rapid Dissolution Formulations * Amount in formula is adjusted for actual potency of TSE-424 as free base. Corresponding adjustment made with Lactose. The formulations given above in Table 1 were prepared by incorporating a portion of the excipients in the granulation and a portion is also added in the final blending steps as dry powders. A dissolution profile generated for the formulations demonstrated almost 90% release of the drug in 30 minutes. Thus, the unique combination of disintegrants and soluble diluents plus the incorporation of both granulated and powdered solids into the composition ensures the fastest release of drug. Wet granulation of the formulations as described in Table 1 may be carried out by mixing the drug and ascorbic acid with a portion of the lactose, microcrystalline cellulose, pregelatinized starch and sodium starch glycolate. The sodium lauryl sulfate is dissolved in the water and used to granulate the mixture of powders in a high shear mixer. The granulation is dried in a fluid bed dryer to a moisture of 2-3%. The particle size of the dried granulation is controlled by passing through a mill equipped with knife-edged blades and using a 20- or 30-mesh screen. The silicon dioxide and remaining lactose, microcrystalline cellulose, pregelatinized starch, and sodium starch glycolate are mixed with the milled granulation in a tumble- type mixer. The final blend is prepared by adding magnesium stearate to the tumble- type mixer and mixing. Compression is carried out on a rotary tablet press using appropriate size tooling. Coating is performed in conventional coating pans and applying the coating suspension to achieve a suitable film coat. Example 2.

Effects on Vasomotor Function in Isolated Rat Aortic Rings Materials and Methods Sprage-Dawley rats (240-260 grams) were divided into 4 groups: (1) Normal non-ovariectomized (intact); (2) Ovariectomized (ovex) vehicle treated; (3) Ovariectomized 17-β estradiol treated (1 mg/kg/day); and (4) Ovariectomized TSE- 424 treated (1 mg/kg/day). All animals were ovariectomized approximately 3 weeks prior to treatment. Each received 1 mg/kg/day of either 17-β estradiol sulfate or TSE- 424 suspended in distilled, deionized water with 1% tween-80 by gastric gavage. Vehicle treated animals received an appropriate volume of the vehicle used in the drug treated groups. Aortic Ring Isolation and Preparation Animals were euthanized by CO2 inhalation and exsanguination. Their thoracic aortas were rapidly removed and placed in 37 C physiological solution with the following composition (mM): NaCl (54.7), KC1 (5.0), NaHCO3 (25.0), MgCl2 « 2H2O (2.5), D-glucose (11.8) and CaCl2 (0.2) gassed with CO2-O2, 95%/5% for a final pH of 7.4. The advantitia was removed from the outer surface and the vessel was cut into 2-3 mm wide rings. Rings were suspended in at 10 mL tissue bath with one end attached to the bottom of the bath and the other to a force transducer. A resting tension of 1 gram was placed on the rings. Rings were equilibrated for 1 hour, signals were acquired and analyzed on-line with a 486-based personal computer and custom software, as well as displayed on a strip chart recorder. Assessment of NO release After equilibration, the rings were exposed to increasing concentrations of phenylephrine (10 ~8 to 10 " M) and the tension recorded. Baths were then rinsed 3 times with fresh buffer. After washout, 200 μM N'-nitro-L-arginine methyl ester hydrochloride (L-NAME) was added to the tissue bath and equilibrated for 30 minutes. The phenylephrine concentration response curve was then repeated. Evaluation of Results Contraction amplitudes at each concentration of phenylephrine were normalized to the maximum phenylephrine-induced contraction before the addition of L-NAME and graphed. The amount of basal NO released was proportional to the degree of separation between the 2 curves before and after L-NAME. Statistical differences were at the p<0.05 level of significance using a repeated measures "Test of Effect Slices (SAS)" analysis of variance. Results All isolated vessels responded to phenylephrine by contracting in a concentration-dependent manner. After washout, vessels from intact animals and animals treated with estradiol and TSE-424 responded with a substantial contraction to L-NAME. Vessels from the vehicle treated group had a significantly smaller response to L-NAME. The amount of basal NO release from the endothelial cells was proportional to the amount of separation between the two curves. The response of the vessels from intact, estradiol and TSE-424 treated was indistinguishable at all phenylephrine concentrations (except 0.0 lμM phenylephrine TSE-424 treated group). However, all three animal groups were significantly different from vehicle treated at the 10 and 100 μM phenylephrine concentrations (p<0.05).
