PTC-209 HBr is the hydrobromide salt of PTC-209, a potent and selective BMI-1 inhibitor (IC50 = 0.5μM). It irreversibly impairs the colorectal tumor growth. [1]BMI-1 is a component of polycomb repressive complex 1 (PRC1) and act as an epigenetic chromatin modifier for a variety of genes. [1]PTC-209 inhibited both UTR-mediated reporter expression and endogenous BMI-1 expression in HCT116 (human colorectal cell) and HT1080 (human fibrosarcoma tumor cell) in a dose dependent manner. In addition, the inhibitory effect of PTC-209 was not from its cytotoxicity. PTC-209 also specifically reduced PRC1 activity. [1]Viable colorectal cancer cell samples treated with PTC-209 ex vivo were injected back to the recipient mice in vivo, the mice exhibited reduced or no tumor growth comparing with the control groups. Thus PTC-209 irreversibly impaired colorectal cancer-initiating cells. Furthermore, in contrast with the control groups, tumor volume was significantly reduced in the colorectal tumor cell transplanted mice following PTC-209 administration.

一般大气压以上5KPA的压力环境就能把水的沸点提高1度;
所以100KPA下的压力锅内的水沸点可以达到120度,所以在这里面杀菌就比在普通的锅里面杀菌效果要好,
当然针对那些怕高温的菌种了;
高压灭菌锅简介
高压灭菌锅又名高压蒸汽灭菌锅,可分为手提式灭菌锅和立式高压灭菌锅。利用电热丝加热水产生蒸汽,并能维持一定压力的装置。主要有一个可以密封的桶体,压力表,排气阀,安全阀,电热丝等组成。高压灭菌锅用途
适用于医疗卫生事业,科研,农业等单位,对医疗器械,敷料,玻璃器皿,溶液培养基等进行消毒灭菌,是理想的设备。手提式高压灭菌锅是食品厂、饮用水厂办QS、HACCP认证的必备检验设备.
高压灭菌锅控制方式
采用微电脑智能化全自动控制,控制灭菌压力,温度,时间;超温自动保护置:超过设定温度,自动切断加热电源;门安全连锁装置:内腔有压力,门盖无法打开,专利装置;低水位报警:缺水时能自动切断电源,声光报警,进口断水检测装置;漏电保护:配置漏电保护装置;温度动态数字显示,灭菌结束发出结束信号;升温、灭菌、排汽、干燥过程自动控制,无须人工监管;模式一:加热-灭菌-排汽;模式二:加热-灭菌-脉冲排汽;模式三:加热-灭菌-不排汽,模式四:自定义。
高压灭菌锅如何使用
1、在外层锅内加适量的水,将需要灭菌的物品放入内层锅,盖好锅盖并对称地扭紧螺旋。
2、加热使锅内产生蒸气,当压力表指针达到 33.78kPa时,打开排气阀,将冷空气排出,此时压力表指针下降,当指针下降至零时,即将排气阀关好。
3、继续加热,锅内蒸气增加,压力表指针又上升,当锅内压力增加到所需压力时,将火力减小,按所灭菌物品的特点,使蒸气压力维持所需压力一定时间,然后将灭菌器断电或断火,让其自然冷后再慢慢打开排气阀以排除余气,然后才能开盖取物。
需要达到103.4kPa(1.05kg/cm2)蒸汽压下,温度达121.3℃的条件。高压蒸汽灭菌法 可杀灭包括芽胞在内的所有微生物。方法是将需灭菌的物品放在高压锅内,加热时蒸汽不外溢,高压锅内温度随着蒸汽压的增加而升高。在103.4kPa(1.05kg/cm2)蒸汽压下,温度达到121.3℃。因为蒸汽不能溢出,而增加了灭菌器内的压力,从而使沸点增高,得到高于100℃的温度。导致菌体蛋白质凝固变性而达到灭菌的目的。
下排气式:敷料,121摄氏度,30min,102.9kPa
器械:121摄氏度,20min,102.9kPa
预真空式:器械、敷料,132~134摄氏度,4min,205.8kPa
