calcein

(S)-Verapamil hydrochloride is an inhibitor of leukotriene C4 (LTC4) and calcein transport by MRP1,and leads to the death of potentially resistant tumor cells.

CP-100356 hydrochloride 是一种具有口服活性和低微摩尔的 MDR1 (P-gp) 和 BCRP 双重抑制剂，是核苷酸衍生的底物类似物，对 MDR1 介导的 Calcein-AM 转运 和 BCRP 介导的 Prazosin 转运有抑制作用。CP-100356 抑制 OATP1B1，可在黑暗中诱导气孔张开。

C8 D-threo Ceramide is a bioactive sphingolipid and cell-permeable analog of naturally occurring ceramides. It is cytotoxic to U937 cells (IC50 = 17 μM) and induces nuclear DNA fragmentation 5- to 6-fold more potently than C8 ceramide . C8 D-threo Ceramide is a substrate for E. coli diacylglycerol kinase. It activates ceramide-activated protein kinase (CAPK) in U937 cells. C8 D-threo Ceramide also enhances V. cholerae cytolysin pore formation in liposome lipid membranes, as measured by calcein release, with a 50% release dose (RD50) value of ~5 μg ml.

C8 L-threo Ceramide is a bioactive sphingolipid and cell-permeable analog of naturally occurring ceramides. It is cytotoxic to U937 cells (IC50 = 10 μM) and, like C8 D-threo ceramide , induces nuclear DNA fragmentation 5- to 6-fold more potently than C8 L-erythro ceramide . C8 D-threo Ceramide also enhances V. cholerae cytolysin pore formation in liposome lipid membranes, as measured by calcein release, with a 50% release dose (RD50) value of ~30 μg ml.

CP 100356 is a specific inhibitor of MDR1 (P-Gp), the protypical ABC transporter. The compound has low uM to nM potency for inhibiting several MDR-1 substrates (calcein-AM, digoxin) in transfected MDCKII cells.

Neridienone B has significant effects on calcein accumulation. Neridienone exhibits significant leishmanicidal activity against amastigotes of L. mexicana.
