ionomycin

Ionomycin 是一种钙离子载体和一种结合钙离子(Ca2+)的抗生素。它是由联合链霉菌(Streptomyces conglobatus)产生的。它在研究中用于提高细胞内钙水平(Ca2+)，并作为了解 Ca2+跨生物膜运输的研究工具。Ionomycin 可促进细胞凋亡，诱导蛋白激酶 C (PKC)活化。

Ionomycin calcium (SQ23377 calcium) 是一种有效的，选择性的钙离子载体 (calcium ionophore)，对二价阳离子具有高度特异性 (Ca>Mg>Sr=Ba)。

KRM-III 是一种具有口服活性的 T 细胞抗原受体 (TCR) 抑制剂，具有抗炎活性，可有效抑制 TCR 和肉豆蔻酸乙酸酯 佛波霉素 离子霉素诱导的 NFAT 核因子活化和 T 细胞增殖，IC50 约为 5 μM。

NKH477 （Colforsin dapropate hydrochloride) 是一种毛喉素衍生物，具有抗抑郁活性，通过对离子霉素敏感的储存位点的作用抑制 ACh 诱导的 Ca2 + 动员。NKH477 是一种腺苷酸环化酶激活剂，具有支气管松弛作用，可抑制 CTL 的产生、MLR 中 T 细胞增殖以及 MLR 中 IL-2 的产生和有丝分裂原反应。

Gliovirin is a fungal metabolite that has been found inT. harzianumand has fungicidal, antimicrobial and anti-inflammatory activities.1It is active against the plant pathogenic fungusP. ultimum(MIC = 60 ng/ml) and the parasiteT. brucei brucei(IC50= 90 ng/ml), but has no effect on the plant pathogenic fungiR. solani,P. omnivorum,T. basicola,R. arrhizus, andV. dahliaeor the bacteriaB. thuringiensis,P. fluorescens, andX. malvacearumwhen used at concentrations up to 1,000 ng/ml.2,3Gliovirin decreases phorbol 12-myristate 13-acetate (TPA)- and ionomycin-induced increased expression of COX-2 (IC50= 1 μM) and protein levels of IL-2 in Jurkat cells (IC50= 5.2 μM).1 1.Rether, J., Serwe, A., Anke, T., et al.Inhibition of inducible tumor necrosis factor-α expression by the fungal epipolythiodiketopiperazine gliovirinBiol.

7β,27-dihydroxy Cholesterol is an oxysterol and agonist of retinoic acid receptor-related orphan receptor γ (RORγ) and RORγt. [1] It activates RORγ- or RORγt-dependent signaling with EC50 values of 691 and 1,045 nM, respectively, in reporter assays using HEK293T cells expressing the recombinant human receptors. 7β,27-dihydroxy Cholesterol is selective for RORγ and RORγt over a panel of eight additional nuclear receptors at 30 µM. It increases IL-17A production in Th17-polarized isolated human na ve CD4+ T cells when used at a concentration of 300 nM. 7β,27-dihydroxy Cholesterol (60 mg kg) increases IL-17A production in isolated mouse γδ T cells stimulated with 12-myristate 13-acetate and ionomycin .

Orlistat-d3 is intended for use as an internal standard for the quantification of orlistat by GC- or LC-MS. Orlistat is a digestive lipase inhibitor. It inhibits diacylglycerol lipase α (DAGLα), DAGLβ, α β-hydrolase domain-containing protein 12 (ABHD12), ABHD16A, and platelet-activating factor acetylhydrolase (PAF-AH; IC50s = 0.06, 0.1, 0.08, 0.03, and 0.05 µM, respectively), as well as pancreatic lipase and hormone-sensitive lipase (IC50s = 0.65 and 2.1 µg ml, respectively) but does not inhibit fatty acid amide hydrolase (FAAH) or KIAA1363 (IC50s = >100 µM for both). Orlistat decreases ionomycin-induced production of the endocannabinoid 2-arachidonoyl glycerol (2-AG) in N18TG2 murine neuroblastoma cells when used at a concentration of 1 µM. It also inhibits fatty acid synthase (FASN; Kiapp = ~0.1 µM for the human enzyme) and the proliferation of PC3 prostate cancer cells in a concentration-dependent manner. Orlistat (10 mg kg) decreases serum cholesterol levels and total bod......

Bexin-1 is an inhibitor of Munc13-4 membrane binding which targets the Munc13-4 C2 domain-membrane interface, and inhibits ionomycin-stimulated ANF-EGFP secretion.
