产品介绍
DL-α-Difluoromethylornithine (hydrochloride hydrate) (DFMO hydrochloride hydrate) 是一种特异性的、不可逆的鸟氨酸脱羧酶抑制剂。 DL-α-二氟甲基鸟氨酸（盐酸盐水合物）是一种治疗非洲锥虫病和女性面部毛发过度生长的药物。

Animal experiment:

Mice: The skin area where the hair is removed is then treated with the eflornithine hydrochloride 13.9% cream (-50 mg per mouse per treatment) using a spatula 2 times a day in an interval of at least 8 h for a maximum period of 36 days[3].

产品描述

DL-α-Difluoromethylornithine (DFMO) is an irreversible inhibitor of ornithine decarboxylase.

Ornithine decarboxylase catalyzes the decarboxylation of ornithine to form putrescine, which is the committed step in polyamine synthesis.

DFMO inhibited the polyamine synthesis process and displayed antiangiogenic and cytostatic effects in many human tumor cells. In rat bladder carcinoma cell line-804G cells, DFMO inhibited the growth of 804G cells stimulated by Fraction I or by 10% FCS [2].

In female SENCAR mice with skin tumorigenesis model, both oral intake of DFMO (1.5-2.0% wt/vol) and intraperitoneal injection of DFMO (20mg,i.p. and 5mg,i.p.) reduced the sizes and numbers of skin tumor compared to control group [3].
