Piperlonguminine
Based on 1 publication(s) in Google Scholar
Piperlonguminine is a cytochrome P450 (CYP450) inhibitor. Piperlonguminine also inhibits the growth of epimastigotes and intracellular amastigotes of Trypanosoma cruzi, with IC50 values of 53.8 and 33.9 μM, respectively. Piperlonguminine regulates HMGB1/TLR4-NF-κB/MAPK-related inflammatory responses, endothelial protein C receptor (EPCR) shedding, melanogenesis, glycolipid metabolism, ischemic brain injury and tumor growth. Piperlonguminine can be used in research on hyperlipidemia, sepsis, Chagas disease, ischemic stroke, sarcoma and severe acute pancreatitis-associated lung injury.

In Vitro
Piperlonguminine (5-40 μM; 6 h; HUVECs) inhibits LPS (HY-D1056)/HMGB1-induced HMGB1 release and RAGE expression, and reduces the increased endothelial barrier permeability induced by HMGB1[2].
Piperlonguminine (5-40 μM; 6 h; HUVECs) inhibits HMGB1-induced expression of VCAM-1, ICAM-1 and E-selectin, as well as THP-1 cell adhesion and transendothelial migration, and reduces TNF-α, IL-6, and signaling associated with NF-κB, ERK1/2 and p38[2].
Piperlonguminine (5-40 μM; 6 h; HUVECs) inhibits LPS-induced production of TNF-α and IL-6, activation of NF-κB p65 and ERK1/2, reduces the expression of VCAM-1, ICAM-1 and E-selectin, and suppresses monocyte adhesion and migration[5].
Piperlonguminine (0.39-25 μg/mL; 72 h) exhibits no significant cytotoxicity in HL-60, HCT-8, SF-295, and MDA-MB-435 cells, with an IC50 >25 μg/mL for all four cell lines[4].
Piperlonguminine (5-40 μM; 6 h; HUVECs) dose-dependently attenuates LPS (100 ng/mL)-induced endothelial barrier disruption, and inhibits TLR4 expression and p38 MAPK phosphorylation; piperlonguminine does not significantly reduce HUVEC viability at concentrations up to 100 μM[5].
Piperlonguminine (10-40 μM; 6 h; HUVECs) inhibits PMA (HY-18739) (1 μM; 1 h)-induced EPCR shedding and TACE/ADAM17 expression, and reduces the phosphorylation of p38, ERK1/2 and JNK; piperlonguminine also inhibits TNF-α- or IL-1β-induced EPCR shedding[7].
Piperlonguminine (0.1-1000 μM; 30 min preincubation; human liver microsomes) exhibits time-dependent inhibition of CYP3A4, CYP2C9, CYP2E1, CYP2C8, and CYP2D6 in the presence of NADPH, with the IC50 values of CYP3A4 and CYP2C9 decreasing to 23.2 μM and 69.0 μM, respectively[6].
Piperlonguminine (100 μM; rat/human liver microsomes; NADPH) forms O-dealkylation metabolite M1 and hydroxylation metabolite M2, as well as four N-acetylcysteine-trapped conjugates M3-M6 derived from O-quinone; CYP3A4 is the major CYP450 enzyme mediating the metabolic activation of Piperlonguminine[6].
Piperlonguminine (6-25 μM; 72 h; B16 cells) dose-dependently inhibits melanogenesis induced by α-MSH (HY-P0252), IBMX (HY-12318) and protoporphyrin IX (HY-B1247), with IC50 values of 9.6, 9.2 and 9.1 μM, respectively, but does not significantly suppress OAG/PKC-mediated melanogenesis[9].
Piperlonguminine (3-25 μM; B16 cells) dose-dependently reduces α-MSH-induced CREB phosphorylation and MITF expression, and downregulates Tyrosinase transcription/expression, but does not directly inhibit the L-DOPA oxidizing activity of cell-free Tyrosinase[9].
Piperlonguminine (1-30 μM; during 3T3-L1 differentiation) promotes triglyceride accumulation and increases 2-deoxyglucose uptake in a concentration-dependent manner, enhances adiponectin release at 10 and 30 μM, and upregulates the mRNA levels of adiponectin, PPARγ2, GLUT4 and aP2; piperlonguminine does not exhibit significant direct PPARγ agonistic activity in assays without nuclear receptor cofactors[8].
Piperlonguminine (3.6-361 μM; 96 h) inhibits the growth of T. cruzi Y strain epimastigotes with an IC50 of 53.8 μM; it inhibits intracellular amastigotes in LLCMK2 cells at 18-361 μM with an IC50 of 33.9 μM. The CC50 of piperlonguminine against LLCMK2 cells is 303.1 μM, with a selectivity index (SI) of 8.9[10].
Piperlonguminine (34 μM; 24 h; *T. cruzi* extracellular amastigotes) increases MDC-labeled autophagic vacuoles, and this change is partially inhibited by wortmannin; ultrastructural and mitochondrial analyses also show that piperlonguminine induces mitochondrial abnormalities, cytoplasmic vacuolization, and alterations in membrane structures[10].
Piperlonguminine (2.5-40 μM; 12 h; SH-SY5Y) concentration-dependently enhances cell viability and reduces apoptosis after 3 h of oxygen-glucose deprivation (OGD)[11].
Piperlonguminine (20 μM; 12 h; SH-SY5Y) inhibits TNF-α (20 ng/mL; 30 min)-induced phosphorylation of p38 MAPK and NF-κB p65[11].

Parmacokinetics
In Vivo
Piperlonguminine (5.5 or 11.0 μg/mouse; i.v.) reduces LPS-induced increases in vascular permeability and peritoneal leukocyte migration in mice[5].
Piperlonguminine (11 μg/mouse; administered 12 h after CLP or at 12 and 50 h after CLP) reduces CLP-induced serum soluble EPCR (sEPCR) levels[7].
Piperlonguminine (11.0 μg/mouse; i.v.; at 12 and 50 h post-CLP) increases the survival rate from 0% to 40% in CLP-induced septic mice[2].
Piperlonguminine (11.0 μg/mouse; i.v.; 12 and 50 h after LPS) increases the survival rate from 0% to 40% in LPS (15 mg/kg; i.p.)-induced septic mice[5].
Piperlonguminine (10 mg/kg; p.o.; once daily for 14 days) reduces total cholesterol (TC), triglycerides (TG) and low-density lipoprotein cholesterol (LDL-C), while increases high-density lipoprotein cholesterol (HDL-C) in high-fat diet-fed Wistar rats; the levels of TC, TG, LDL-C and HDL-C are 9.67, 1.47, 3.57 and 1.31 mmol/L, respectively, compared with 22.26, 2.86, 5.44 and 0.68 mmol/L in the high-fat diet control group[3].
Piperlonguminine (25 or 50 mg/kg; i.p.; once daily for 7 days) reduces tumor weight in Sarcoma 180 tumor-bearing mice, with tumor growth inhibition rates of 38.71% and 40.68%, respectively[4].
Piperlonguminine (2.4 mg/kg; i.p.; immediately after reperfusion) reduces neurological deficit scores, cerebral infarction volume and brain water content, and alleviates increased blood-brain barrier (BBB) permeability in a rat model of focal cerebral ischemia; the cerebral infarction volume decreases from 22.9% in the vehicle group to 14.7%[11].
Piperlonguminine (5, 10, or 15 mg/kg; i.p.; 24 h) dose-dependently alleviates pancreatic and pulmonary tissue injury, alveolar thickening, and edema in rats with severe acute pancreatitis induced by 4% sodium taurocholate (HY-N0545). A dose of 10 mg/kg achieves the main experimental effect, so 10 mg/kg is used in subsequent mechanism experiments[12].
Piperlonguminine (10 mg/kg; i.p.; 24 h) reduces serum TNF-α, IL-1β and IL-6 by 27.57%, 44.91% and 51.29%, respectively, in rats with severe acute pancreatitis. It also downregulates NOX2, NOX4, ROS, MPO, IL-1β, TLR4 and NF-κB signaling in lung tissues, while decreasing the phosphorylation of IκB-α and p65[12].
