Biological Activity
| ln Vitro | In HeLa cells (EC50=6.23 μM), SU3327 (Compound 9) can prevent TNF-α-stimulated c-Jun phosphorylation[1]. Polymorphonuclear leukocyte (PMN) rolling and attachment to human brain microvascular endothelial cells (hCMEC/D3) is efficiently reduced by SU3327 (25 nM). It also inhibits AP-1 activation and drastically lowers VCAM-1 expression[3]. |
| ln Vivo | In diabetic electrode models, SU3327 (Compound 9; 25 mg/kg; intraperitoneal injection; cosmetic BKS.Cg-+Leprdb/+Leprdb/+Leprdb/OlaHsd db/db electrode) can recuperate the insulin electrodes' processing capacity [1]. |
| Animal Protocol |
Animal/Disease Models: Male BKS.Cg-+Leprdb/+Leprdb/OlaHsd db/db mice (11 weeks old) were injected with insulin [1]. ] Doses: 25 mg/kg Route of Administration: intraperitoneal (ip) injection Experimental Results: Resulted in a statistically significant reduction in blood glucose levels. |

| Additional Infomation | Halicin is a member of the class of thiadiazoles that is 1,3,4-thiadiazol-2-amine which is substituted by a (5-nitro-1,3-thiazol-2-yl)sulfanediyl group at position 5. It is a c-Jun N-terminal kinase inhibitor (IC50 = 0.7uM) and exhibits antibacterial properties. It has a role as a c-Jun N-terminal kinase inhibitor and an antibacterial agent. It is a member of thiadiazoles, a member of 1,3-thiazoles, a primary amino compound, a C-nitro compound and an organic sulfide. |
Solubility Data
| Solubility (In Vitro) | DMSO : ~62.5 mg/mL (~239.19 mM) |
| Solubility (In Vivo) |
Solubility in Formulation 1: ≥ 2.08 mg/mL (7.96 mM) (saturation unknown) in 10% DMSO + 40% PEG300 + 5% Tween80 + 45% Saline (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 20.8 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: ≥ 2.08 mg/mL (7.96 mM) (saturation unknown) in 10% DMSO + 90% (20% SBE-β-CD in Saline) (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 20.8 mg/mL clear DMSO stock solution to 900 μL of 20% SBE-β-CD physiological saline solution and mix evenly. Preparation of 20% SBE-β-CD in Saline (4°C,1 week): Dissolve 2 g SBE-β-CD in 10 mL saline to obtain a clear solution.  (Please use freshly prepared in vivo formulations for optimal results.) |
