Biological Activity
| ln Vivo | The plasma levels of IL-6, TNF-α, E-selectin, ICAM-1, and VCAM are dramatically reduced by GS-6201 (CVT-6883) (4 mg/kg; i.p.; every 12 hours for 14 days) [ 2]. Left and right ventricular hypertrophy and dysfunction were brought on by GS-6201 (4 mg/kg; intraperitoneal; every 12 hours for 14 days); these effects were markedly reduced after 7 days and persisted after 14 and 28 days [2]. The oral GS-6201 (2 mg/kg) therapy showed a Cmax of 1110 ng/mL, a dAUC of 6500 ng·h/mL, and a t1/2 of 4.25 hours, respectively [1]. |
| Animal Protocol |
Animal/Disease Models: Adult outbred male CD1 mice (8-12 weeks old, AMI model) [2] Doses: 4 mg/kg Route of Administration: intraperitoneal (ip) injection; every 12 hrs (hrs (hours)) for 14 days Experimental Results: IL-6 , TNF-α, E-selectin, ICAM-1 and VCAM plasma levels were Dramatically diminished. Animal/Disease Models: SD (SD (Sprague-Dawley)) rat[1] Doses: 2 mg/kg Route of Administration: po (pharmacokinetic/PK/PK analysis) Experimental Results: Cmax, dAUC and t1/2 were 1110 ng/mL, 6500 ng·h/ mL and 4.25 hrs (hrs (hours)). |

Solubility Data
| Solubility (In Vitro) | DMSO : ~100 mg/mL (~224.00 mM) |
| Solubility (In Vivo) |
Solubility in Formulation 1: 2 mg/mL (4.48 mM) in 10% DMSO + 40% PEG300 + 5% Tween80 + 45% Saline (add these co-solvents sequentially from left to right, and one by one), suspension solution; with sonication. For example, if 1 mL of working solution is to be prepared, you can add 100 μL of 20.0 mg/mL clear DMSO stock solution to 400 μL PEG300 and mix evenly; then add 50 μL Tween-80 to the above solution and mix evenly; then add 450 μL normal saline to adjust the volume to 1 mL. Preparation of saline: Dissolve 0.9 g of sodium chloride in 100 mL ddH₂ O to obtain a clear solution. Solubility in Formulation 2: ≥ 2 mg/mL (4.48 mM) (saturation unknown) in 10% DMSO + 90% Corn Oil (add these co-solvents sequentially from left to right, and one by one), clear solution. For example, if 1 mL of working solution is to be prepared, you can add 100 μL of 20.0 mg/mL clear DMSO stock solution to 900 μL of corn oil and mix evenly.  (Please use freshly prepared in vivo formulations for optimal results.) |
