الوصف (Description)

Pitstop2 is a clathrin inhibitor that inhibits amphoteric binding of clathrin terminal domains with an IC50 value of 12μM[1-2].

In Hela cells, Pitstop2 (5-30µM) inhibits clathrin-independent endocytosis in a dose-dependent manner. In BEAS-2B and COS-7 cells, Pitstop2 (20μM) inhibits the uptake of transferrin and major histocompatibility complex class I (MHCI) proteins[3]. Pitstop2 inhibits gridin-mediated transferrin uptake in HeLa and U2OS cells with IC50 values of 12-15μM and 9.7μM, respectively [1].

Pitstop2 (10µg/kg) pretreatment can partially prevent nitroglycerin (NTG)-induced hyperalgesia in rat chronic migraine (CM) model. Compared with NTG+ vehicle group, Pitstop2 can significantly reduce the expression of CGRP and c-Fos in trigeminal ganglion (TG) and reduce the activation of trigeminovascular system (TVS) in CM rats [4].

البروتوكول (Protocol)

Cell experiment [1]:

Cell lines

ARPE-19 cells

Preparation Method

ARPE-19 cells were treated with 10μM pitstop2, 30μM dyngo4A, 80μM dynasore or vehicle control (DMSO) for 30 min. The expression of p-AKT was detected by western blot assay.

Reaction Conditions

10μΜ, 30min

Applications

ARPE-19 cells treated with 10μM pitstop2 ablated epidermal growth factor (EGF)-stimulated Akt phosphorylation.
Animal experiment [2]:

Animal models

Rat model of chronic migraine

Preparation Method

The rats were divided into four groups: Saline, Nitroglycerin (NTG, i.p.), NTG + vehicle and NTG + Pitstop2 (i.n.). The NTG + Pitstop2 group was given Pitstop2 every other day, followed by NTG 30 minutes later. Behavioral tests were performed 20 minutes before i.n. administration and two hours after i.p. injection.

Dosage form

10µg/kg, Two days a day for nine days, i.n.

Applications

Pitstop2 can significantly increase the threshold of basic mechanical pain and thermal pain, and reverse NTG-induced acute mechanical pain and thermal pain allergy.

إرشادات عامة
اختر مذيبًا مناسبًا وفقًا لبيانات ذوبانية المنتج. بعد التحضير، قسّم المحلول المخزون إلى أجزاء لتجنب دورات التجميد والذوبان المتكررة.
استخدم المحاليل المخزونة خلال 6 أشهر عند حفظها في -80°C، أو خلال شهر واحد عند حفظها في -20°C.
لتحسين الذوبانية، سخّن الأنبوب إلى 37°C وعرّضه للموجات فوق الصوتية لمدة مناسبة.
شروط الشحن
تُشحن عينات التقييم مع عبوات تبريد. وتُشحن الأحجام الأخرى المتاحة في درجة حرارة الغرفة، أو مع عبوات تبريد عند الطلب.
