背景
甲磺酸溴隱亭最早由諾華公司開發(fā),主要用于抗震顫麻痹,抑制生理性泌乳和治療催乳激素過高引起的經(jīng)前期綜合征、肢端肥大癥、女性不育癥和亨丁頓舞蹈病。臨床用于治療帕金森病,與催乳素有關(guān)的生殖系統(tǒng)功能異常,如閉經(jīng)、溢乳癥、經(jīng)前綜合征、產(chǎn)褥期乳腺炎、纖維囊性乳腺瘤、男性陽痿或性欲減退,還可用于垂體腺瘤等。甲磺酸溴隱亭快速釋放的口服制劑輔助用于Ⅱ型糖尿病的治療,該藥2009年5月獲得FDA批準(zhǔn)。
作用
本品又稱溴麥亭、溴化麥角隱亭、溴克丁、麥角克堿、麥角環(huán)肽、抑乳停、甲磺酸溴隱亭,是麥角生物堿的半合成衍生物,能特異地興奮中樞多巴胺受體,對(duì)其他受體有拮抗作用。無麥角類的收縮子宮和血管作用??梢种芇RL、LH的分泌,激活腦內(nèi)新紋狀體的多巴胺受體,控制震顫麻痹綜合征;通過中樞或外周的作用松弛血管平滑肌,減低交感神經(jīng)興奮性,進(jìn)而使血壓下降,脈率不增加。
適應(yīng)癥
適用于治療高泌乳素血癥及泌乳素瘤,或作為泌乳素瘤的術(shù)前準(zhǔn)備或術(shù)后治療;亦用于治療垂體生長激素瘤、巨人癥及肢端肥大癥;或用于垂體促皮質(zhì)素瘤及庫欣(Cushing)病合并血糖升高者的治療??捎糜谥委煻嗄衣殉簿C合征,對(duì)排卵功能障礙性不孕癥有效。對(duì)乳腺增生、回乳、月經(jīng)紊亂、經(jīng)前緊張綜合征、肝性腦病、糖尿病、特發(fā)性水腫、垂體性甲亢及甲狀腺功能減退癥均有一定效果。
制備

甲磺酸溴隱亭的合成路線

1)溴隱亭的合成

將α-麥角隱亭12g(20.8mmoL)和二氯甲烷120mL加入反應(yīng)瓶中,攪拌溶清后依次加入5,5-二溴巴比妥酸3.69g(12.9mmoL)、33%氫溴酸的冰乙酸溶液0.2mL,控溫25~30℃反應(yīng)5~6h,過濾,濾液依次用1moL/L的硫代硫酸鈉(30mL),5%的碳酸氫鈉溶液(30mL),20%氯化鈉溶液(30mL)洗滌。有機(jī)相用無水硫酸鎂干燥,過濾,并加入硅膠36g濃縮將溶劑完全拉干。柱層析:流動(dòng)相先為二氯甲烷,后為V(二氯甲烷)∶V(丙酮)=6∶1的混合溶液。得10.6g溴隱亭,收率78%。

2)甲磺酸溴隱亭的合成

將溴隱亭6.0g用二氯甲烷120mL溶清后加入2-丁酮200mL,控制內(nèi)溫20~30℃,加入甲磺酸1.14g,生成結(jié)晶型沉淀,攪拌1h。濾出固體,用2-丁酮30mL洗滌,干燥得6.13g甲磺酸溴隱亭,收率86%。

生物活性
Bromocriptine mesylate 是一種有效的多巴胺 D2/D3 受體激動(dòng)劑,結(jié)合多巴胺 D2 受體,pKi 為 8.05±0.2。
靶點(diǎn)

pKi: 8.05±0.2 (dopamine D2 receptor)

體外研究

Bromocriptine stimulates [ 35 S]-GTPγS binding at D2 dopamine receptor expressed in CHO cells with pEC 50 of 8.15±0.05. Bromocriptine also is a strong inhibitor of brain nitric oxide synthase. The ergot alkaloid Bromocriptine (BKT) is found to act as a strong inhibitor of purified neuronal nitric oxide synthase (NOS) (IC 50 =10±2 μM) whereas it is poorly active towards inducible macrophage NOS (IC 50 >100 μM) . Bromocriptine is found to inhibit the activity of at least one human cytochrome P450 enzyme. Bromocriptine is a potent inhibitor of CYP3A4 with a calculated IC 50 value for the interaction of 1.69 μM.

體內(nèi)研究

Bromocriptine mesylate (2 mg/kg, i.p.) is administered for 7 days in groups of mice in forced swimming test (FST) and tail suspension test (TST). Bromocriptine group shows significant anti-immobility action as compared to control. When Bromocriptine administered 30 min after the last dose of 7 days MPE treatment and subjected to FST, this dopaminergic agonist produces significant and dose dependent potentiation of anti-immobility action of MPE (200 mg/kg, p.o.) as compared to MPE treatment alone. Bromocriptine treatment group shows a significant reduction of immobility time as compared to control. Bromocriptine administration after 7 days pretreatment with MPE (100 and 200 mg/kg, p.o.) shows significant and dose dependent potentiation of anti-immobility action of MPE as compared to MPE treatment alone. Intracisternal administration of Bromocriptine decreases significantly the static mechanical allodynia (SMA) score compared to that of sham (saline-injected rats) and its effect lasted for 30 min. Intraperitoneal administration of Bromocriptine induces a significant, dose dependent (0.1 mg and 1 mg/kg) decrease in pain scores in CCI-IoN group when compared to sham and its effect lasted for 6 h. The highest dose induces the highest score decrease (P<0.01). Bromocriptine effect lasts for 20 min. Intraperitoneal administration of Bromocriptine induces a significant dose dependent decrease in SMA score in CCI-IoN+6-OHDA lesioned group compared to that of sham. Its effect lasts for 6 h.
