Catenarin
Catenarin, an anthraquinone compound, inhibits CCR5- and CXCR4-mediated chemotaxis. Catenarin reduces the phosphorylation of mitogen-activated protein kinases (p38 and JNK) and their upstream kinases (MKK6 and MKK7), and calcium mobilization. Catenarin shows anti-inflammatory effect and suppresses leukocyte migration in the diabetes. Catenarin exhibits significant inhibitory effects against Gram-positive bacteria. Catenarin prevents type 1 diabetes (T1D) in nonobese diabetic mice[1][2].

Catenarin (0-2.5 μg/mL, 1 h) inhibits CCR5 (IC50 = 0.24 μg/mL) mediated chemotaxis in JK-EF1α-CCR5 cells and CXCR4 (IC50 = 0.46 μg/mL) mediated chemotaxis in Jurkat cells[1].
Catenarin (1-5 μg/mL, 1 h) inhibits calcium mobilization in CCR5 and CXCR4 pathways in JK-EF1α-CCR5 cells and Jurkat cells[1].
Catenarin (1 μg/mL, 0-15 min) inhibits the activation of MAPK cascades in CCR5 and CXCR4 pathways in JK-EF1α-CCR5 cells and Jurkat cells[1].
Catenarin (1 μg/mL, 1 h) does not affect surface expression of CCR5 and CXCR4 receptors in JK-EF1α-CCR5 cells or Jurkat cells[1].
Catenarin (0.1-0.2 μg/mL, 0-10 h) exhibits significant inhibitory effects against Gram-positive bacteria with a minimum inhibitory concentration (MIC) of 1 μg/mL in complex media and 0.2 μg/mL in synthetic media[2].
