名稱(chēng) | Betrixaban maleate |
描述 | Betrixaban is a non-vitamin K oral anticoagulant whose action is driven by the competitive and reversible inhibition of the factor Xa [1]. It was selected among all lead compounds due to its low hERG channel affinity while sustaining its factor Xa inhibition capacity [3]. Betrixaban, now developed by Portola Pharmaceuticals Inc., is prescribed as a venous thromboembolism (VTE) prophylactic for adult patients with moderate to severe restricted motility or with other risks for VTE [2]. VTE can be manifested as deep vein thrombosis or pulmonary embolism and it is a leading cause of preventable death in hospitalized patients [4]. |
激酶實(shí)驗(yàn) | To measure the inhibition of fXa activity by direct fXa inhibitors and the reversal of its inhibitory effect by r-Antidote, purified human plasma fXa (3 nM) (Haematologic Technologies), varying concentrations of inhibitor (0, 2.5, 5.0 and 7.5 nM) and r-Antidote are added to the assay buffer (20 mM Tris, 150 mM NaCl, 5 mM Ca2+ and 0.1% BSA, pH 7.4). After incubation at room temperature for 30 min, 100 μM Spectrozyme-fXa is added to the mixture, and the initial rate of sub?strate cleavage is monitored continuously for 5 min at 405 nm in a 96-well plate reader. The initial velocity of product formation as a function of inhibitor and r-Antidote concentrations is analyzed by Dynafit to estimate the binding affinity of r-Antidote to each inhibitor[2]. . |
動(dòng)物實(shí)驗(yàn) | Whole-blood INR values (mean±s.d.) in rats infused with Betrixaban (1 mg/kg per hour) or vehicle and then treated with either vehicle or r-Antidote by i.v. bolus (6 mg) over 5 min plus infusion (9 mg/h) for up to 90 min. Circles, vehicle+vehicle; squares, Betrixaban + vehicle; triangles, Betrixaban + r-Antidote. *P≤0.02 compared to the r-Antidote treatment group determined by unpaired two-tailed t test. Whole-blood INR values (mean±s.d.) in rats infused with Apixaban (0.5 mg per kg body weight h?1) or vehicle and then treated with either vehicle or r-Antidote by i.v. bolus (6 mg) over 5 min plus infusion (6 mg/h) for up to 90 min. Circles, vehicle + vehicle; squares, apixaban + vehicle; triangles, apixaban+r-Antidote. *P≤0.01 compared to the r-Antidote treatment group determined by unpaired two-tailed t test. |
體外活性 | 在膜片夾持hERG實(shí)驗(yàn)中,Betrixaban的IC50為8.9 μM。對(duì)于Betrixaban,血漿激肽釋放酶的IC50和Ki值分別為6.3 μM和3.5 μM。Betrixaban(hERG Ki 1.8 μM)展示的hERG活性顯著低于所有其他化合物(hERG Ki≤0.5 μM)。 |
體內(nèi)活性 | 靜脈注射(IV)0.5 mg/kg及口服(PO)2.5 mg/kg時(shí),Betrixaban在犬體內(nèi)的生物利用度為51.6%;靜脈注射0.75 mg/kg及口服7.5 mg/kg時(shí),Betrixaban在猴子體內(nèi)的生物利用度為58.7%[1]。Betrixaban和Apixaban引起的全血國(guó)際標(biāo)準(zhǔn)化比值(INR)增加均可被r-Antidote類(lèi)似地逆轉(zhuǎn)。三種fXa抑制劑(每種分別給藥)靜脈輸注30分鐘后,rivaroxaban、Betrixaban和apixaban的總血漿濃度分別為1.4±0.4 μM、0.2±0.01 μM和1.4±0.3 μM,未結(jié)合抑制劑的百分比分別為2.2%±0.8%、40%±7.2%和1.5%±0.3%。r-Antidote給藥后,抑制劑的總血漿濃度增至1.9±0.09 μM、2.0±0.4 μM和4.2±0.7 μM,未結(jié)合抑制劑的百分比降至0%、0.3%±0.1%和0.05%±0.02%。因此,對(duì)于這三種抑制劑,r-Antidote將凝血酶原時(shí)間修正至接近正常值,與抑制劑的自由分?jǐn)?shù)降低相關(guān)聯(lián)[2]。 |
