商品描述
  • Ingenol-3-hexanoate was more potent in reactivating latent HIV than other known activators such as SAHA, ingenol 3,20-dibenzoate, TNF-α, PMA and HMBA. Ingenol-3-hexanoate alone was able to reactivate virus transcription in primary HIV-infected latent cells up to 12 fold, and up to 25 fold in combination with SAHA. Pandeló José D., et al. "Reactivation of latent HIV-1 by new semi-synthetic ingenol esters." Virology 462-463: 328-339 (2014).
  • Synthetic ingenol derivatives referred to as ingenol A, B, and C activated the HIV-LTR in reporter cell lines and latent virus in human PBMCs at concentrations as low as 10 nM. They were also able to inhibit the replication of HIV-1 subtype B and C in MT-4 cells and human PBMCs with EC50 values of 0.02 and 0.09 µM respectively. Abreu C.M., et al. "Dual role of novel ingenol derivatives from Euphorbia tirucalli in HIV replication: inhibition of de novo infection and activation of viral LTR." PLoS One 9: e97257 (2014).
  • Highly active antiretroviral therapy (HAART) effectively suppresses HIV viral replication; however, it fails to eradicate latent viral reservoirs. Ingenol-3-hexanoate is a potent activator of latent HIV reservoirs, possibly via protein kinase C[delta]-Nf-[kappa]B signaling. Jiang G., et al. "Reactivation of HIV latency by a newly modified Ingenol derivative via protein kinase Cδ-NF-κB signaling." AIDS 28: 1555-1566 (2014).

LC Labs的关于纯度的更多信息我们知道许多情况下,由于不合格试剂的虚假结果,导致无法识别的纯度问题导致大量研究工作受到损害,甚至变得毫无用处。以下是信号转导试剂业务中产品纯度或活性问题的一些示例:几年前,一家主要的供应商向许多实验室提供了错误的激酶抑制剂H7异构体。错误的异构体具有明显不同的生物学特性,并且由此获得的结果也不正确。我们上级组织的科学家检测到了这个问题,并与一个合作的学术实验室一起发布了更正的数据[ Biochem。生物物理学。Res。通讯 187:657-663(1993)]。冈田酸产品存在很大的稳定性问题。冈田酸虽然散装形式相当稳定,但细分为亚毫克量并真空干燥以最终销售后,其降解率可立即高达40%或更高。许多供应商没有对包装后的最终产品进行适当的测试,我们的分析表明,其他一些供应商的冈田酸在某些情况下的纯度不足60%。客户一再告诉我们,冈田酸比其他供应商的原料更具活性。白屈菜红碱氯化物由于一些人们不了解的问题而引起了极大的动荡。首先,多年来,我们注意到白屈菜红碱的其他一些来源也被大量的生物活性杂质污染,例如血红碱,很难从天然来源的白屈菜红碱中去除。相比之下,我们的白屈菜红碱是通过严格的多步方法制备的,其中包括HPLC和结晶步骤,并且所得纯度极高且可重现。第二,研究人员告知我们,其他供应商的白屈菜红碱在不同批次之间显示出不同的生物活性。第三,在一些出版物中建议白屈菜红碱没有显示出最初归因于1991年的有效的PKC抑制活性[ Biochem.Chem.Soc。,1993,5,2,3]。生物物理学。Res。通讯 172:993-999(1991)]。1991年的这份报告使用了从天然来源分离的白屈菜红碱,它可能已经被抑制PKC催化活性的干扰化合物所污染。但是,可能不会排除其他更复杂的解释。但却是很清楚,白屈菜红有力块多效应的PKC活化剂,如佛波醇酯,但有可能的是,这些影响从PKC的相互作用,不涉及实际的激酶活性的抑制导致本身。据报道,1994年Rottlerin是PKCδ的选择性抑制剂,但最近的研究未能显示出在相似浓度下任何PKC抑制活性。1994年的研究使用了来自植物来源的rottlerin,当我们分析多个批次时,该物质一直被证明含有大量杂质。随后,非常有能力的实验室未能复制原始的rottlerin结果,以及其他考虑因素,迫使我们停止生产该产品。单击此处,可以在我们的rotterlin产品页面上找到更多信息。来自三个不同的非附属学术实验室的研究人员告知我们,我们的PMA在各种生物系统中的性能要优于从其他来源获得的材料。
