Polmacoxib (CG 100649) is a first-in-class NSAID drug candidate, is a dual inhibitor of carbonic anhydrase (CA) and COX-2. Polmacoxib inhibits premalignant and malignant colorectal lesions in mouse models, partly through inhibiting tumor cell proliferation.

Polyphyllin D induces apoptosis via the mitochondrial apoptotic pathway as evidenced by decreased Bcl-2 expression levels, disruption of MMP and increased Bax, cytochrome C, and cleaved-caspase-3 levels. Polyphyllin D has an anti-angiogenic effect. Polyphyllin D has toxicity in human RBCs as well as its underlying mechanism for the hemolysis and eryptosis/erythroptosis. Polyphyllin D has strong anticancer activity, can overcome drug resistance in R-HepG2 cells and elicit programmed cell death via mitochondrial dysfunction.

1. Polyphyllin VI has hemostasis , expectorant , bacteriostasis, anticytotoxic, anti pregnancy kill sperm effects.

Pancreatic Polypeptide, rat acetate is an agonist of NPY receptor, with high affinity at NPYR4.

Pancreatic Polypeptide (human) acetate is a C-terminally amidated 36 amino acid peptide, which acts as a neuropeptide Y (NPY) Y4/Y5 receptor agonist.

2,3,5,4'-Tetrahydroxystilbene 2-O-β-D-glucoside (Astragalus polyphenols) is a compound isolated from the roots of Polygonum species, which inhibits the formation of 5-HETE, HHT, and thromboxane B2.

Polyphyllin G (Polyphyllin VII), the the main member of polyphyllin family, shows strong anticancer activity against several carcinomas, including lung cancer, breast cancer, colorectal cancer, cervical cancer, hepatocellular carcinoma and osteosarcoma.

Polyphyllin II (Chonglou Saponin II) has hemostasis, expectorant, bacteriostasis, anticytotoxic, anti-pregnancy kill sperm effects.

[cPP1-7,NPY19-23,Ala31,Aib32,Gln34]-hPancreatic Polypeptide is a potent and selective neuropeptide Y Y5 receptor agonist, exhibiting a binding affinity with an IC50 of 0.24 nM for the hY5 receptor, and significantly stimulates food intake [1].

Gastric Inhibitory Polypeptide (1-30), porcine, deficient in the 12 C-terminal amino acids of the natural gastric inhibitory polypeptide (GIP), demonstrates biological activity by enhancing the release of insulin and somatostatin [1].

Pancreatic polypeptide, a peptide produced by the pancreas's endocrine PP cells, modulates pancreatic secretory functions and influences hepatic glycogen levels and gastrointestinal secretion [1].

Polyphemusin II-Derived Peptide (T140), a CXCR4 inhibitor, effectively blocks HIV-1 entry and hinders the binding of the anti-CXCR4 monoclonal antibody (12G5) to CXCR4 [1].

Polyphemusin I, an amphiphilic antiparallel β-hairpin peptide stabilized by two disulfide bridges, comprises 18 amino acids and exhibits potent antimicrobial activity against both Gram-negative and Gram-positive bacteria [1].

Human membrane-bound PD-L1 polypeptide serves as an antigen for inducing the production of PD-L1 antibodies [1].

Polyporusterone C (Compound 3), a natural product extracted from Polyporus umbellatus, exhibits cytotoxic activities, displaying IC50 values of 37, 26, and 42 μg/mL against L-1210 cells after 3, 5, and 7 days of treatment, respectively [1].

Polyporoid C, an ergostane-type ecdysteroid, demonstrates significant in vivo anti-inflammatory activity [1].

Polyporoid B, an ergostane-type ecdysteroid, demonstrates significant anti-inflammatory effects in vivo [1].

Polypectate sodium, a principal constituent of cell wall polysaccharides (pectins), serves as a carbon source and triggers polygalacturonase production. It is also employed to assess alkaline-active and stable pectate lyases from Streptomyces spp., and to investigate the optimization of polygalacturonase synthesis from Xanthophyllum spp. under various reaction conditions [1].

Gastric Inhibitory Polypeptide (6-30) amide (human) is an incretin hormone used in diabetes research [1].

Antifreeze Polypeptide 6 (winter flounder) is one of the winter flounder's antifreeze polypeptides, which depresses the freezing point of plasma by inhibiting the expansion of ice nuclei [1].

Polyprenol (13~21) (Polyprenol mixture (13~21)) is a type of neutral lipid.
