Melflufen（Melphalan Flufenamide）盐酸盐（0.5-10 μM；24 小时）以浓度依赖性方式降低 MM.1S、INA-6、RPMI-8226、MM.1R、Dox-40、ARP-1、和 ANBL-6 细胞[1]。当暴露于盐酸美氟芬时，MM.1S 细胞会发生凋亡[1]。另一种强效外泌体分泌激活剂是盐酸美氟芬[3]。

在异种移植小鼠模型中，盐酸美氟芬（美法仑氟芬酰胺）（3 mg/kg；静脉注射；每周两次，持续两周）表现出抗 MM 作用 [1]。

Melphalan Flufenamide Hydrochloride is the hydrochloride salt form of melphalan flufenamide, a peptide-drug conjugate composed of a peptide conjugated, via an aminopeptidase-targeting linkage, to the alkylating agent melphalan, with potential antineoplastic and anti-angiogenic activities. Upon administration, the highly lipophilic melphalan flufenamide penetrates cell membranes and enters cells. In aminopeptidase-positive tumor cells, melphalan flufenamide is hydrolyzed by peptidases to release the hydrophilic alkylating agent melphalan. This results in the specific release and accumulation of melphalan in aminopeptidase-positive tumor cells. Melphalan alkylates DNA at the N7 position of guanine residues and induces DNA intra- and inter-strand cross-linkages. This results in the inhibition of DNA and RNA synthesis and the induction of apoptosis, thereby inhibiting tumor cell proliferation. Peptidases are overexpressed by certain cancer cells. The administration of melphalan flufenamide allows for enhanced efficacy and reduced toxicity compared to melphalan.

Drug Indication
Pepaxti is indicated, in combination with dexamethasone, for the treatment of adult patients with multiple myeloma who have received at least three prior lines of therapies, whose disease is refractory to at least one proteasome inhibitor, one immunomodulatory agent, and one anti-CD38 monoclonal antibody, and who have demonstrated disease progression on or after the last therapy. For patients with a prior autologous stem cell transplantation, the time to progression should be at least 3 years from transplantation (see section 4. 4).

10% DMSO → 40% PEG300 → 5% Tween-80 → 45% ddH2O (或 saline);
假设最终工作液的体积为 1 mL, 浓度为5 mg/mL: 取 100 μL 50 mg/mL 的澄清 DMSO 储备液加到 400 μL PEG300 中，混合均匀/澄清；向上述体系中加入50 μL Tween-80，混合均匀/澄清；然后继续加入450 μL ddH2O (或 saline)定容至 1 mL；
3、溶剂前显示的百分比是指该溶剂在最终溶液/工作液中的体积所占比例;
4、 如产品在配制过程中出现沉淀/析出，可通过加热(≤50℃)或超声的方式助溶;
