原产地英文商品名：BENDAMUSTINE(TREANDA Generic) 100mg/3ml/vial
Anger et al.公开了苯达莫司汀对浆细胞瘤病人成功应用的最初临床结果。苯达莫司汀从1971年到1992年以Cytostasan的商品名由耶拿制药公司生产。从1993年后，这种细胞生长抑制剂被ribosepharm GmbH公司以Ribomustine的商品名上市。
本品用于何杰金病、非何杰金淋巴瘤、多发性骨髓瘤、CLL和乳腺癌。其剂量血癌为50～60 mg/m2/d,3～5天或每3～4周为100～120 mg/m2 ;实体瘤每4 周为120～150 mg/m2 ,每日1 次,30～60 min 静脉滴注。盐酸苯达莫司汀作为单用或联合化疗,对何杰金病和非何杰金淋巴瘤的治疗反应率分别为61%～97%和41%～48 %。
对多发性骨髓瘤病人,苯达莫司汀/泼尼松治疗的完全反应率较高(32 %) ,美法仑/ 泼尼松疗法反应更持久。在环磷酰胺、长春新碱、泼尼松治疗方案中,苯达莫司汀取代环磷酰胺,对发展中低度毒性非何杰金淋巴瘤有相似的反应率。在环磷酰胺、甲氨蝶呤、氟尿嘧啶治疗方案中,苯达莫司汀取代环磷酰胺,使转移性乳腺癌病人的缓解期从6.2 个月延长至15.2个月。
盐酸苯达莫司汀( bendamustine) 是双功能基烷化剂,体外对人卵巢癌和乳腺癌有细胞毒性,体外与环磷酰胺、美法仑(melphalan) 、卡莫司汀(carmustine)和顺铂有部分交叉耐受。对乳腺癌细胞系MCF7抑制细胞生长的IC50为138μmol/L,对顺铂抗药性卵巢癌细胞系A27802CP2 的IC50为157μmol/L ,对多柔比星抗药性乳腺癌细胞系MCF7AD 的IC50为187μmol/L。
在等毒性浓度( IC50s)下,苯达莫司汀比美法仑、环磷酰胺或卡莫司汀引起更多的DNA 双螺旋断裂,比卡莫司汀或环磷酰胺作用更持久。体外引起浓度依赖性的B2慢性淋巴细胞白血病(B2CLL) 细胞凋亡,与氟达拉滨(fludarabine) 合用,在48 h 内凋亡率高1.4 倍。在Ⅰ期临床试验中,苯达莫司汀60～80 mg/m2每周1次,至8周,对顽固性实体瘤病人引起持久性的全淋巴细胞减少,主要为B细胞毒性。4周后,外周血B细胞、自然杀伤细胞和T 细胞分别下降90%,70%和60%以上。
