Biological Activity
| ln Vitro | E64FC26 has anti-MM action with an EC50 of 0.59 μM (0.01-100 μM; 24 hours) [1]. E64FC26 demonstrated notable cytotoxicity in genetically varied multiple myeloma (MM) cell lines (KMS11, OPM2, MM.1S BzR, MM.1S, SA-13, U266 BzR, ANBL6, KMS12PE, U266, 8226 DxR, 8226 BzR, KMS12BM, H929, 8226 cells) [1]. |
| ln Vivo | In an NSG mouse model, intraperitoneal administration of E64FC26 (2 mg/kg; three days per week for seven days) demonstrated anti-MM effects, extending the median survival by 2 weeks [1]. The two treatments that increased survival the most were bortezomib and E64FC26, which extended median survival by 20 days [1]. In CD-1 mice, the pharmacokinetics of E64FC26 were assessed. The intravenous administration of E64FC26 (2 mg/kg; gray trace) or side-study (5 mg/kg; blue trace) resulted in the measurement of drug concentrations during a 24-hour period. A single mouse dose of 5 mg/kg resulted in systemic exposure that reached a maximum concentration (Cmax) of 400 nM with a terminal half-phase decline of 9.5 hours, indicating sufficient local bioavailability in CD-1 mice. 34% [1]. Scenario mode Vk*MYC E64FC26 is continuously administered during the day (2 mg/kg, intraperitoneal injection, 3 days/week). In all mice, E64FC26 can cause an instant anti-MM reaction and reduce serum M protein by 33 ± 7.9% on average [1]. |

Solubility Data
| Solubility (In Vitro) | DMSO : ~100 mg/mL (~293.79 mM) |
| Solubility (In Vivo) |
Solubility in Formulation 1: ≥ 2.5 mg/mL (7.34 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 25.0 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.) |
