实验参考方法

Animal experiment:

Mice[3]Soblidotin (Auristatin PE) and Vinorelbine are dissolved in 0.05 M sodium lactate buffer (pH 4.5) and in PBS, respectively. Mice are treated every 7 d with PD184352 (200 mg/kg) or vehicle by oral administration (four times per day, every 6 h) and with Auristatin PE (0.25-2.5 mg/kg), Vinorelbine (5-20 mg/kg), or vehicle by i.v. injection (once per day, 1 h after the first PD184352 administration). Tumor volume is measured with digital calipers and calculated according to the following formula: (longest diameter)×(shortest diameter)2/2. Body weight, tumor volume, and toxicities are noted every 2 to 4 d for the duration of the experiment.

产品描述

Soblidotin (Auristatin PE) is a novel synthetic Dolastatin 10 derivative and inhibitor of tubulin polymerization.

Soblidotin (Auristatin PE) is a novel synthetic dolastatin 10 derivative that inhibits tubulin polymerization. Soblidotin (Auristatin PE) exhibits antitumor activity against p-glycoprotein-overexpressing cell lines established from colon cancer H116 and breast cancer-resistant protein-positive cell lines established from lung cancer PC-6, and is more potent than Vincristine, Paclitaxel, and Docetaxel against these cell lines[1]. Soblidotin (Auristatin PE) is a synthetic analog of dolastatin 10 which inhibits the growth of several tumoral cell lines and induces caspase-3-dependent apoptosis. Soblidotin (Auristatin PE) also shows antitumoral activity in Vincristine-, Docetaxel-, and Paclitaxel-resistant tumors, which makes it a potential chemotherapy drug for use in tumors which do not respond to other microtubule inhibitors[2].

Intravenous injection of Auristatin PE (TZT-1027) has been shown to potently inhibit the growth of P388 leukemic cells and several solid tumors in mice, and to prolong the survival of the animals, and its antitumor efficacy has been shown to be superior or comparable to that of the reference agents Dolastatin 10, Cisplatin, Vincristine, and 5-Fluorouracil. Furthermore, in xenograft models, Auristatin PE reduces intratumoral blood perfusion 1 to >24 h after its administration, thereby producing hemorrhagic necrosis of the tumors[1]. Auristatin PE (Soblidotin) shows antivascular effects in tumoral models overexpressing VEGF and in murine colon tumors, with an increase in vascular permeability, vessel closure, and widespread hemorrhage[2]. Mice bearing subcutaneous HT-29 tumors (200 mm3) are dosed every 7 days with Auristatin PE (0.5 or 1.0 mg/kg) for a total of four cycles. Under such conditions, Auristatin PE (TZT-1027) inhibits the growth of HT-29 xenografts in a dose-dependent manner. Coadministration of Auristatin PE does not interfere with the PD184352-induced suppression of ERK1/2 phosphorylation. Immunostaining for Ki-67 as a marker for proliferating cells confirmed that the number of such cells in tumor sections is decreased greatly at 24 hours after the initial dosing with PD184352 compared with that apparent for vehicle-treated tumors. Auristatin PE treatment alone increases the number of TUNEL-positive cells in HT-29 xenografts by 24 hours in a dose-dependent manner, and this effect is enhanced by coadministration of PD184352[3].

Loading Auristatin PE onto boron nitride nanotubes and their effects on the apoptosis of Hep G2 cells

Colloids Surf B Biointerfaces 2019 Sep 1;181:305-314.PMID:31154141DOI:10.1016/j.colsurfb.2019.05.047.

Auristatin PE (PE) as an anti-microtubule agent possesses good anticancer activity. However, the poor target effect and strong side effect limit the clinical application of PE. Boron nitride nanotubes (BNNTs) represent an outstanding carrier candidate providing a wise choice for liver-targeted drug delivery. A drug delivery system based on BNNTs and PE (BNNTs-PE) against liver cancer cells was designed and constructed in this study. Firstly, BNNTs were prepared and hydroxylated, subsequently, PE was loaded onto BNNTs by noncovalent conjugation and was stable at neutral pH but released at pH 4.49. It was found that BNNTs-PE demonstrates an enhanced anticancer activity against Hep G2 cells in comparison with free PE. BNNTs-PE kills cancer cells in a manner of mitochondria-mediated apoptosis pathway through reducing the mitochondrial membrane potential, activating caspase cascade. This BNNTs-PE system may be very promising for the treatment of liver cancer in the future.

A new tubulin polymerization inhibitor, Auristatin PE, induces tumor regression in a human Waldenstrom's macroglobulinemia xenograft model

Int J Oncol 1999 Aug;15(2):367-72.PMID:10402249DOI:10.3892/ijo.15.2.367.

Waldenstrom's macroglobulinemia (WM) is an uncommon lymphoproliferative disease which remains incurable with current treatment protocols. We have previously established a permanent WM cell line, WSU-WM, which grows as a xenograft in severe combined immune deficient (SCID) mice. In this study, we investigated the anti-tumor effects of Auristatin PE (a structural modification of the marine, shell-less mollusk peptide constituent dolastatin 10). WSU-WM cells were cultured in RPMI-1640 at a concentration of 2x10(5) cells/ml using 24-well plates. Auristatin PE or dolastatin 10 were added to triplicate wells and cell count and viability were assessed after 24, 48 and 72 h. Results showed that both agents were active against WSU-WM, and were able to induce complete growth inhibition at 100 pg/ml. The efficacy of these agents in vivo was evaluated using the WSU-WM SCID mouse xenograft model. Auristatin PE and dolastatin 10 were given i.v. via tail vein at 2.0 mg/kg and 0.2 mg/kg, respectively. The agents were given every second day for three injections which represent the maximum tolerated doses. Tumor growth inhibition (T/C), tumor growth delay (T-C), and log10 kill for Auristatin PE and dolastatin 10 were 0%, 18 days, 2.83 and 67%, 2 days, 0.06, respectively. Based on these animal results, dolastatin 10 was inactive while Auristatin PE was highly active. We therefore focused further investigation on Auristatin PE to understand some of its mechanisms of action. Using two flow cytometry assays, propidium iodide for cell cycle analysis and 7-amino actinomycin D (7AAD) to detect apoptosis, we were able to demonstrate that Auristatin PE at 10 pg/ml after 24 h arrested 50% of WSU-MW cells in G2M. Concomitantly, 31% of auristatin PE-treated cells entered apoptosis. By 72 h, greater than 75% of the cells became apoptotic. The activity of Auristatin PE should be evaluated in other tumor types and in clinical trials.

Successful treatment of human chronic lymphocytic leukemia xenografts with combination biological agents Auristatin PE and bryostatin 1

Clin Cancer Res 1998 May;4(5):1337-43.PMID:9607595doi

We tested the activity of dolastatin 10 (a natural product derived from the shell-less marine mollusk, Dolabella auricularia, a sea hare) and its structural modification, Auristatin PE, alone and in combination with bryostatin 1 (a protein kinase C activator derived from the marine bryozoan Bugula neritina) on a human B-cell chronic lymphocytic leukemia cell line (WSU-CLL) and in a severe combined immune deficient (SCID) mouse xenograft model bearing this cell line. WSU-CLL cells were cultured in RPMI 1640 at a concentration of 2 x 10(5)/ml using a 24-well plate. Agents were added to triplicate wells, and cell count, viability, mitosis, and apoptosis were assessed after 24 h of incubation at 37 degrees C. Results showed that dolastatin 10 had no apparent inhibition of cell growth at concentrations less than 500 pg/ml. Auristatin PE, on the other hand, showed significant growth inhibition at concentrations as low as 50 pg/ml. Auristatin PE-treated cultures, at this concentration, exhibited 27 and 4.5% mitosis and apoptosis, respectively. Dolastatin 10, at the same concentration, did not exert any effect and was comparable with that of control cultures. In the WSU-CLL-SCID mouse xenograft model, the efficacy of these agents alone and in combination with bryostatin 1 was evaluated. Tumor growth inhibition (T/C), tumor growth delay (T-C), and log10 kill for dolastatin 10, Auristatin PE, and bryostatin 1 were 14%, 25 days, and 1.98; 2%, 25 days, and 1.98; 19%, 13 days, and 1.03, respectively. Auristatin-PE produced cure in three of five mice, whereas dolastatin 10 showed activity but no cures. When given in combination, Auristatin PE + bryostatin 1-treated animals were all free of tumors (five of five) for 150 days and were considered cured. Dolastatin 10 + bryostatin 1-treated animals produced cure in only two of five mice. We conclude that: (a) auristatin-PE is more effective in this model than dolastatin 10; (b) Auristatin PE can be administered at a concentration 10 times greater than dolastatin 10; (c) there is a synergetic effect between these agents and bryostatin 1, which is more apparent in the bryostatin 1 + Auristatin PE combination. The use of these agents should be explored clinically in the treatment of CLL.
