Biological Activity
| ln Vitro | CLZ-8 (compound 8) (0-160 μM, 48 h) strongly suppresses apoptosis that is dependent on PUMA [1]. In a dose-dependent way, CLZ-8 (0–1 μM, 2 hours) markedly increased the vitality of irradiation cells, considerably shielded HUVEC, and suppressed overexpressed PUMA [2]. Radiation-induced apoptosis is attenuated by CLZ-8 (0-1 μM, 24 hours) [2]. HUVEC is protected against DNA fragmentation by CLZ-8 (1 μM, 2 hours) [2]. |
| ln Vivo | Mice treated with CLZ-8 (0-400 mg/kg; ig; once) have strong anti-radiation effects [2]. |
| Cell Assay |
Apoptosis analysis[1][2] Cell Types: DLD-1 cells or HUVEC Cell Tested Concentrations: 0-160 μM (DLD-1) or 0.01, 0.1 and 1 μM (HUVEC) Incubation Duration: 48 hrs (hours) (DLD-1 ) or 24 hrs (hours) (HUVEC) Experimental Results: Dramatically inhibited PUMA-dependent apoptosis with an IC50 of 38.93 ± 0.91 μM. Attenuates radiation-induced apoptosis. Western Blot Analysis [2] Cell Types: HUVEC Cell Tested Concentrations: 0.001, 0.01, 0.1 and 1 μM Incubation Duration: 2 h Experimental Results: PUMA induction was inhibited and p53 levels were Dramatically diminished after radiation. Dramatically diminished MCL-1 levels and increased Bcl-XL levels. |
| Animal Protocol |
Animal/Disease Models: 6-8 weeks old male balb/c (Bagg ALBino) mouse [2] Doses: 100, 200 and 400 mg/kg Route of Administration: intragastric (po) (po)administration once 30 minutes before irradiation. Experimental Results: Improved survival rate of irradiated mice. |

Solubility Data
| Solubility (In Vitro) | DMSO : ~50 mg/mL (~127.06 mM) |
| Solubility (In Vivo) |
Solubility in Formulation 1: ≥ 0.83 mg/mL (2.11 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 8.3 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.) |
