一般說明

化学结构:紫杉醇

應用

紫杉醇已用于研究其在胰腺导管腺癌小鼠模型中对肿瘤消退的作用[1]。紫杉醇也已用作多西他赛色谱分析的内标[2]。此外,紫杉醇已被用于分析其对秀丽隐杆线虫胚胎的影响[3]

生化/生理作用

紫杉醇是一种有效的抗肿瘤和抗有丝分裂的紫杉烷类药物,可与 β-微管蛋白的N端结合,并使微管稳定,使细胞周期停滞在G2/M期。微管损伤通过依赖 JNK 的途径诱导细胞凋亡,随后通过不依赖 JNK 的途径诱导细胞凋亡,这可能与蛋白激酶 A(PKA)或 Raf-1 激酶的激活,进而导致 Bcl-2 磷酸化有关。通过 CYP2CB 的主要代谢物是 6α-羟基紫杉醇(6α-OHP)。
紫杉醇高度亲脂。它用作 p-糖蛋白(一种多药耐药蛋白)的底物。因此,紫杉醇较少定位在大脑中。除了杀细胞作用外,紫杉醇还可以刺激肿瘤的侵袭过程。[4]

Laulimalide is a microtubule-binding drug that was originally isolated from marine sponges. High concentrations of laulimalide stabilize microtubules and inhibit cell division similarly to paclitaxel; however, there are important differences with respect to the nature of the specific cellular defects

Paclitaxel (PTX) is one of the most effective broad-spectrum chemotherapeutic agents in the treatment of cancers. However, its clinical application has been limited due to its poor water solubility. Its current clinical administration uses the adjuvant of serious side effects

Questions

1–2 of 2 Questions  
  1. Is there any validated method available for performing the hplc of paclitaxel (cat no. T7191)

    1 answer
    1. This product is intended for research use only and testing methods are considered proprietary. However, historical information indicates the following conditions for HPLC analysis:
      Column: Supelcosil LC 18-F 25 cm x 4.6 mm ID Part. size 5 um
      Mobile Phase: Time: 0 MIN 30 MIN
      A. Acetonitrile 30 % 60 %
      B. Water 70 % 40 %

      Flow Rate: 1.5 ml/min
      Solv: Methanol
      Conc: 0.5 mg/ml
      Vol. Inj: 10 ul
      Detection: 227 nm

      RT = approximately 5.4 (Major)

      Helpful?

  2. what is the wavelength of maximum absorption for paclitaxel (cat no. t7191) dissolved in methanol?

    1 answer
    1. The maximum absorption for paclitaxel dissolved in methanol has not been determined. However, various sources state that the absorption maximum in methanol is 227, 273 nm. This information has not been validated.
