代谢
在利用人肝S9的实验研究中,Arbaclofen placarbil并未显示出是CYP1A2、CYP2C19、CYP2D6、CYP2E1和CYP3A4的底物。Arbaclofen placarbil,作为R-arbaclofen的酰氧基烷基碳酸酯前药,据信会通过酯酶酶人体羧酸酯酶-2水解成母胺,R-baclfen。也预期会产生等摩尔的二氧化碳、异丁酸和异丁醛。利用质谱和气相色谱,已经体外证实了异丁酸的产生。
In experimental studies using human liver S9 Arbaclofen placarbil was not shown to be a substrate for CYP1A2, CYP2C19, CYP2D6, CYP2E1, and CYP3A4. Arbaclofen placarbil, the acyloxyalkyl carbamate prodrug of R-arbaclofen, is believed to undergo hydrolysis by the esterase enzyme human carboxylesterase-2 into the parent amine, R-baclfen. Carbon dioxide, isobutyric acid, isobutyraldehyde, are also expected to be produced in equimolar quantities. The productions of isobutyric acid has been confirmed in vitro untilizing mass spectrometry and gas chromatography.

吸收、分配和排泄
  • 吸收
与巴氯芬不同,R-巴氯芬(阿巴氯芬)的吸收并不仅限于上部小肠。阿巴氯芬在整个胃肠道中的吸收能力使得能够开发出持续释放制剂,阿巴氯芬普卡拉比尔(AP)。在一项对10名健康志愿者的AP吸收研究中,一次20mg口服AP剂量,在食物存在的情况下,达到Tmax为5.05小时。在大鼠中,当AP剂量为10mg/kg时,R-巴氯芬的口服生物利用度为44 ± 12%,当剂量为1mg/kg时,口服生物利用度为68 ± 6%。在猴子和狗中,当口服AP时,R-巴氯芬的口服生物利用度很高:分别为94 ± 16%和92 ± 7%。相比之下,口服R-巴氯芬的生物利用度在猴子和狗中分别为39 ± 21%和49 ± 20%。在大鼠和猴子中进行的研究测量了通过结肠内给药后R-巴氯芬的生物利用度,结果显示R-巴氯芬的生物利用度较低(分别为7 ± 3%和3 ± 2%),而通过结肠内给药AP悬浮液的R-巴氯芬生物利用度显著较高(在大鼠和猴子中分别为37 ± 9%和37 ± 15%)。AP悬浮液的结肠内给药在狗中也导致了R-巴氯芬的高生物利用度(77 ± 23%)。整个肠道的吸收既包括被动吸收也包括主动吸收,并且通过单羧酸类型1转运体发生。
Unlike baclofen, absorption of R-baclofen(arbaclofen) is not limited to the upper small intestine. The ability of arbaclofen to be absorbed throughout the gastrointestinal tract allowed for the development of the sustained release formulation, arbaclofen placarbil (AP). In one study of AP absorption in 10 healthy volunteers, one 20mg oral dose of AP, in the presence of food, resulted in a Tmax of 5.05h. The oral bioavailability of R-baclofen in rats when AP was dosed at 10mg/kg was 44 ± 12%, and when dosed at 1mg/kg, oral bioavailability was 68 ± 6%. In monkeys and dogs, the oral bioavailability of R-baclofen when AP was orally dosed was high: 94 ± 16%, and 92 ± 7%, respectively. In comparison, when oral R-balofen was dosed oral bioavailability was 39 ± 21% in monkeys and 49 ± 20% in dogs. Colonic absorption studies measuring R-baclofen bioavailability post intracolonic dosing in rats and monkeys, have revealed low bioavailability with the administration of R-baclofen (7 ± 3% and 3 ± 2%, respectively), and significantly higher R-baclofen bioavailability with intracolonic dosing of AP suspension ( 37 ± 9% and 37 ± 15%, in rats and monkeys respectively). Intracolonic dosing of AP suspension also resulted in high biolavailability of R-baclofen in dogs (77 ± 23%). Absorption throughout the intestine is both passive and active and occurs via the monocarboxylate type 1 transporter.

  • 消除途径
作为R-巴氯芬,84-88%通过肾脏消除。小于1%通过粪便消除。

吸收、分配和排泄
  • 分布容积
放射性标记显示AP在体内广泛分布。组织分布主要发生在肾脏和肝脏。

吸收、分配和排泄
  • 清除
静脉注射AR的大鼠血清除率为15.81 ± 10.2 L/h/kg。相比之下,静脉注射R-巴氯芬的大鼠、猴子和狗的半衰期范围为1.6-3.4小时,其中大鼠的总血清除率为0.51± 0.13L/h/kg,猴子的总血清除率为0.31±0.11L/h/kg,狗的总血清除率为0.24L±0.01L/h/kg。在利用放射性示踪剂附着在R-巴氯芬的研究中,97%的放射性活性在尿液中回收。
Blood clearance of an IV bolus of AR in rats resulted in a total blood clearance of 15.81 ± 10.2 L/h/kg in rats. In comparison, blood clearance of an IV bolus of R-baclofen in rats, monkeys, and dogs, resulted in half lives ranging from 1.6-3.4hours, with total blood clearances reported to be 0.51± 0.13L/h/kg in rats, 0.31±0.11L/h/kg in monkeys, and 0.24L±0.01L/h/kg in dogs. (2) In studied utilizing radioactive tracers attached to R-baclofen, 97% of radioactivity was recovered in the urine.

    the multi-kilogram synthesis of a novel transported pro-drug of R-baclofen. The key steps in the synthesis were the enzyme-catalyzed kinetic resolution of isopropyl(methylthiocarbonyloxy)methyl-2-methylpropionate using Candida antarctica lipase A to provide the desired (S)-enantiomer. This was followed by the reaction with sulfuryl chloride and N-hydroxysuccinimide to produce (S) 1-(2,5-dioxoazolidi
