Piper longum Linn.

Piperlongumine is a alkaloid, possesses ant-inflammatory, antibacterial, antiangiogenic, antioxidant, antitumor, and antidiabetic activities. Piperlongumine induces ROS, and induces apoptosis in cancer cell lines. Piperlongumine shows anti-cardiac fibrosis activity, suppresses myofibroblast transformation via suppression of the ERK1/2 signaling pathway. Piperlongumin could be used in the study of migrasome.

5,6-Dihydropyridin-2(1H)-one (1,5,6-Trihydropyridin-2-one) is a Sesquiterpenoids product that can be isolated from the leaves of Alpinia intermedia.

Pipernonaline is a piperine derivative with antiprostate cancer activity. Pipernonaline inhibits the proliferation of androgen-dependent/independent LNCaP/PC-3 prostate cells. Pipernonaline activates caspase-3 and promotes procaspase-3/PARP cleavage. Pipernonaline also mediates reactive oxygen species (ROS) production, increased intracellular Ca(2+), and mitochondrial membrane depolarization.

Aristolactam A II (Aristololactam A II) is a weak COX inhibitor with cytotoxic and anti-plasmodial activities. Aristolactam A II exhibits inhibitory activity against Chloroquine (HY-17589A)-sensitive strains, and exerts its inhibitory effect on Plasmodium falciparum growth by inducing cell membrane damage marked by LDH release. Aristolactam A II can be applied to the research of malaria-related mechanisms.

(2E,4Z-Decadienoyl)piperidine is a herbicide found in the fruits of Piper longum L..

(2E,4Z,8E)-Dehydropipernonaline is a natural product that can be found in Biba.

Schisphenin A is a natural product that can be found in Chang Sheng Qi.

(2E)-Decenoylpiperidide (Compound 12) is a Sarmentine (HY-W099725) analogue. (2E)-Decenoylpiperidide shows phytotoxicity on barnyard grass.

Piperchabamide B is an amide alkaloid. Piperchabamide B can be isolated from the fruits of Piper longum. Piperchabamide B exhibits anticancer activity against acute promyelocytic leukemia, non-small cell lung cancer, and breast cancer.

Piperundecalidine is an amide alkaloids that can be purified from Piper longum L. Piperundecalidine shows various biological properties, such as anti-inammatory, analgesic, anti-amoebic, anti-depressant, hepatoprotective,etc..

Sarmentine is a broad-spectrum contact herbicide and PSII inhibitor, with an IC₅₀ of 3.0 μM and a K_i of 1.5 μM against spinach, an IC₅₀ of 1.72 μM against wild-type Amaranthus retroflexus, and an IC₅₀ of 0.97 μM against triazine-resistant Amaranthus retroflexus. Sarmentine competitively binds to the Q_B binding site of plastoquinone on PSII, thereby blocking photosynthetic electron transport. Sarmentine inhibits enoyl-ACP reductase in Arabidopsis thaliana by targeting the early fatty acid synthesis process, with an IC₅₀ of 18.3 μM. Sarmentine induces light-independent loss of plasma membrane integrity and electrolyte leakage. Sarmentine also exhibits antiplasmodial, antimycobacterial, antituberculous, and antiplatelet aggregation activities.

5,6-Dihydropyridin-2(1H)-one (Standard) is the analytical standard of 5,6-Dihydropyridin-2(1H)-one (HY-W006454). This product is intended for research and analytical applications. 5,6-Dihydropyridin-2(1H)-one (1,5,6-Trihydropyridin-2-one) is a Sesquiterpenoids product that can be isolated from the leaves of Alpinia intermedia.
