Tetracycline hydrochloride exhibits activity against a wide range of bacteria including gram-positive, gram-negative bacteria, chlamydiae, mycoplasmas and rickettsiae. Tetracycline hydrochloride can be used for the research of infections.

(E/Z)-4-Hydroxytamoxifen (Afimoxifene) is a racemic compound of (Z)-4-Hydroxytamoxifen and (E)-4-Hydroxytamoxifen isomers. (E/Z)-4-Hydroxytamoxifen is a selective estrogen receptor modulator with mixed estrogenic and antiestrogenic activity, which is also an active metabolite of Tamoxifen (HY-13757A). (E/Z)-4-Hydroxytamoxifen is an agonist of the G protein-coupled estrogen receptor (GPER) with relatively low affinity (100-1000 nM). (E/Z)-4-Hydroxytamoxifen is promising for research of cyclical mastalgia, such as breast pain, tenderness, and nodularity.

Coelenterazine is a luminescent enzyme substrate for apoaequorin and Renilla luciferase. Renilla luciferase and substrate coelenterazine has been used as the bioluminescence donor in bioluminescence resonance energy transfer (BRET) to detect protein-protein interactions. Coelenterazine is a superoxide anion-sensitive chemiluminescent probe and it can also be used in chemiluminescent detection of peroxynitrite (Ex/Em = 429/466 nm).

Pterostilbene is a stilbenoid isolated from blueberries and Pterocarpus marsupium. Shows anti-oxidant, anti-inflammatory, anti-carcinogenic, anti-diabetic and anti-obesity properties. Pterostilbene blocks ROS production, also exhibits inhibitory activity against various free radicals such as DPPH, ABTS, hydroxyl, superoxide and hydrogen peroxide.

Daidzein is a soy isoflavone, which acts as a PPAR activator.

Caffeic acid is an inhibitor of both TRPV1 ion channel and 5-Lipoxygenase (5-LO).

Isoliquiritigenin is an anti-tumor flavonoid from the root of Glycyrrhiza uralensis Fisch., which inhibits aldose reductase with an IC₅₀ of 320 nM. Isoliquiritigenin is a potent inhibitor of influenza virus replication with an EC₅₀ of 24.7 μM.

Verbascoside is isolated from Acanthus mollis, acts as an ATP-competitive inhibitor of PKC, with an IC₅₀ of 25 μM, and has antitumor, anti-inflammatory and antineuropathic pain activity.

Isoquercetin (Quercetin 3-glucoside) is a naturally occurring polyphenol that has antioxidant, anti-proliferative, and anti-inflammatory properties. Isoquercetin alleviates ethanol-induced hepatotoxicity, oxidative stress, and inflammatory responses via the Nrf2/ARE antioxidant signaling pathway. Isoquercetin regulates the expression of nitric oxide synthase 2 (NO2) via modulating the nuclear factor-κB (NF-κB) transcription regulation system. Isoquercetin has high bioavailability and low toxicity, is a promising candidate agent to prevent birth defects in diabetic pregnancies.

Scutellarin, an active flavone isolated from Scutellaria baicalensis, can down-regulates the STAT3/Girdin/Akt signaling in HCC cells, and inhibits RANKL-mediated MAPK and NF-κB signaling pathway in osteoclasts. Scutellarin is active against HIV-1IIIB, HIV-1(74V) and HIV-1KM018 with EC₅₀s of 26 μM, 253 μM and 136 μM, respectively.

Mycophenolate mofetil (RS 61443) is the morpholinoethylester proagent of Mycophenolic acid. Mycophenolate mofetil inhibits de novo purine synthesis via the inhibition of inosine monophosphate dehydrogenase (IMPDH). Mycophenolate mofetil shows selective lymphocyte antiproliferative effects involve both T and B cells, preventing antibody formation.

Isorhamnetin is a flavonoid compound extracted from the Chinese herb Hippophae rhamnoides L.. Isorhamnetin suppresses skin cancer through direct inhibition of MEK1 and PI3K.

Isoginkgetin is a pre-mRNA splicing inhibitor inhibitor. Isoginkgetin also inhibits activities of both Akt, NF-κB and MMP-9. Isoginkgetin inhibits the activity of the 20S proteasome, induces apoptosis and activates autophagy.

Oleuropein, found in olive leaves and oil, exerts antioxidant, anti-inflammatory and anti-atherogenic effects through direct inhibition of PPARγ transcriptional activity. Oleuropein induces apoptosis in breast cancer cells via the p53-dependent pathway and through the regulation of Bax and Bcl2 genes. Oleuropein also inhibits aromatase.
