產品描述
花萼海綿體誘癌素A（Calyculin A，CAS NO：101932-71-2）最初是從海綿Disodermia calyx中分離到的一種海洋毒素，是一種具細胞滲透性、有效和選擇性的蛋白磷酸酶1（PP1，IC50=0.3-0.7 nM）和蛋白磷酸酶2A（PP2A，IC50=0.5-1.0 nM）抑制劑。對PP2B和PP2C的選擇性＞10,000,000倍。對酸性或堿性磷酸酶或磷酸-酪氨suan蛋白磷酸酶無抑制。Calyculin A抑制平滑肌肌球蛋白B內源性磷酸酶的活性，誘導肌肉纖維收縮，并伴隨細胞質游離Ca2+水平提高。花萼海綿體誘癌素A還是一種非佛波類的腫瘤促進劑。與小鼠皮膚上的蛋白磷酸酶結合，誘導鳥氨suan脫羧酶（ODC）活性，進而促進腫瘤生長。

Biomed Res Int. 2017:9795271.PMID: 28680886 體外研究： 細胞類型（Cell type）：Platelet-rich plasma (PRP) sample 藥物配制（Preparation）：Calyculin-A (CLA) was dissolved in DMSO 實驗方法（Assay）：PRP (110μL) was preincubated with either HEPES buffer containing 0.5% DMSO as control or the protein phosphatase inhibitor CLA (50nM), for 30 minutes at 37°C in a water bath. After preincubation, platelets were activated either by TRAP (20μM) or by thiomersal (200mM) for 15 minutes at 37°C in a water bath. Then PRP (5μL) was stained with 5μL monoclonal CD41-PE antibody and 5μL Annexin-V-FITC and Annexin-V binding buffer (1x concentrate) was added to examine the PS-expression of the platelets. |

PMID: 9405704 體外研究： 細胞類型（Cell type）：Xenopus Oocytes 藥物配制（Preparation）：Calyculin A was prepared in 100% ethanol as a 1 mM stock solution. Immediately after dilution in distilled water to the appropriate concentration, calyculin A was microinjected into the oocytes according to the RNA injection protocol. 實驗方法（Assay）：The NMDA-induced currents of striatal mRNA-injected oocytes were measured before and 8 min after 1-min application of 50 μM forskolin or before and 12 min after 1-min application of 10 nM PMA. The same protocol was followed after injecting oocytes with calyculin A to a final intracellular concentration of 500 nM 60–90 min before voltage-clamping. The intracellular concentration of calyculin A was calculated by assuming standard oocytes with a volume of 0.5 μl. |

PMID: 17381845 體外研究： 細胞類型（Cell type）：Living crane-fly spermatocytes 藥物配制（Preparation）：Calyculin A was dissolved in DMSO as a 1mM or 50 μM stock solution. 實驗方法（Assay）：Living crane-fly spermatocytes were perfused with insect Ringer's solution or with Calyculin A in insect Ringer's solution, at final concentrations of 0.5 μM, 100 nM, 50 nM, 20 nM, 10 nM or 5 nM, prepared from a 1 mM or a 50 μM Calyculin A stock in DMSO. Results showed that concentrations of 5 nM and 10 nM had no effect on anaphase chromosome movement, 20 nM had inconsistent effects, and 50 nM had consistent effects. Thus we used 50 nM for most of the experiments. |
