NS-398 生物活性

靶点

COX-2

COX-2, IC50:3.8 μM

描述

NS-398 is a novel anti-inflammatory and analgesic agent. The COX-1 activity was completely unaffected by 100μ M NS-398, whereas the COX-2 activity was concentration-dependently inhibited with IC50 of 3.8μ M^[3]. NS-398 shows the anti-inflammatory and analgesic effects with the effective dose range being 0.3∼5 mg/kg in rats^[4].In vitro experiments, NS-398 inhibited the proliferation and maturation of differentiated myogenic precursor cells, which suggested a detrimental effect on skeletal muscle healing. In the NS-398-treated mice, muscle regeneration delayed at early time points after injury^[5].NS-398 decreased the regeneration of injured muscle by delaying the maturation of regenerating myofibers, and promoted fibrosis by up-regulating TGF-β1 expression. NS-398 administration also reduced the inflammatory response and up-regulated myostatin expression^[5]. NS-398 (10 mM) can induce apoptosis in LNCaP cells^[6]. When treated with NS-398, the C4-2b cells were observed to continue to proliferate and continued to retain malignant phenotype characteristics. NS-398 treatment resulted in C4-2b cell differentiation into an unusual neuroendocrine-like cell which produced both epithelial and neuronal proteins. Moreover, this C4-2b cellular response to NS-398 was mediated by NF-kappa beta transcription factor activation^[6]. Cox-2 is involved in the pathogenesis of Noise-induced hearing loss (NIHL), and pre-treatment with the Cox-2 inhibitor NS398 could inhibit Cox-2 expression during noise overstimulation attenuating noise-induced hearing loss and hair cell damage^[7].

溶解方案

细胞实验：

DMSO: 35 mg/mL(111.34 mM)，配合低频超声助溶，注意：DMSO长时间开封后，会吸水并导致溶解能力下降，请避免使用长期开封的DMSO

动物实验：请根据您的动物给药指南选择适当的溶解方案。
以下溶解方案都请先按照体外实验的方式配制澄清的储备液，再依次添加助溶剂：
——为保证实验结果的可靠性，澄清的储备液可以根据储存条件，适当保存；体内实验的工作液，建议现用现配，当天使用；以下溶剂前显示的百分比是指该溶剂在终溶液中的体积占比；如在配制过程中出现沉淀、析出现象，可以通过加热和/或超声的方式助溶
