Emodin (Frangula emodin) is a naturally occurring anthraquinone present in the roots and barks of numerous plants; exerts antiproliferative effects in Y cells that are regulated by different signaling pathways.

SARS-CoV MPro-IN-2 effectively inhibits the SARS-CoV-2 main protease (M pro), crucial for the virus's replication and transcription in host cells, with an IC50 value of 72.07 nM. Given its significant role in processing viral polyproteins, M pro is regarded as a key target in drug discovery efforts. Consequently, SARS-CoV MPro-IN-2 holds promise for COVID-19 research.

Sarsasapogenin (Parigenin) is a steroidal sapogenin, that is the aglycosidic portion of a plant saponin. It is named after sarsaparilla (Smilax sp.), a family of climbing plants found in subtropical regions. It was one of the first sapogenins to be identified, and the first spirostan steroid to be identified as such.

Leupeptin hemisulfate is a protease inhibitor with cell membrane-permeable, reversible, competitive, and oral activities. Leupeptin hemisulfate inhibits the activity of Cathepsin B, Cathepsin H, and Cathepsin L, and blocks fusion of amphipathic lysosomes. Leupeptin hemisulfate also has anti-inflammatory activity.

Urolithin M5 (Decarboxyellagic acid) is a neuraminidase inhibitor isolated from olive leaves with antiviral and anticancer and antitumor activities. Urolithin M5 can be used to study influenza A virus infection and SARS-CoV-2 infection.

Chloroquine is a Toll-like receptor inhibitor that inhibits autophagy. Chloroquine has anti-malarial and anti-inflammatory activity and is widely used in the treatment of malaria and rheumatoid arthritis. Chloroquine also has anti-SARS-CoV-2 (COVID-19) activity and anti-HIV-1 activity.

Thapsigargin is a natural product, an inhibitor of sarcoplasmic endoplasmic reticulum Ca2+ ATPase (SERCA) and an endoplasmic reticulum stress inducer. Thapsigargin increases cytoplasmic calcium concentration by blocking the ability of cells to pump calcium into the sarcoplasmic and endoplasmic reticulum.

Cepharanthine (NSC-623442) is a natural alkaloid that inhibits TNF-α-mediated NFκB stimulation, plasma membrane lipid peroxidation, and platelet aggregation, as well as cytokine production. Cepharanthine exhibits anti-inflammatory, antioxidant, and antitumor activities.

Chloroquine phosphate (Aralen phosphate) is an aminoquinoline antimalarial and also is widely used as an autophagy inhibitor. Chloroquine also is an inhibitor of toll-like receptors (TLRs).

Ivermectin (MK-933) is an activator of glutamate-gated chloride channels (GluCls) with antiparasitic activity.

Mizoribine (NSC-289637) belongs to the family of 1-Ribosyl-imidazolecarboxamides. Mizoribine has been investigated for the treatment of Rheumatoid Arthritis.

Acetyl-L-carnitine hydrochloride (Acetyl L-carnitine hydrochloride) is a nutritional supplement composed of the hydrochloride salt form of the acetylated form of the endogenously produced L-carnitine, with potential neuroprotective, cognitive-enhancing, anti-depressive and immunomodulating activities. It may also relieve peripheral neuropathy induced by chemotherapy, diabetes or other diseases. In addition, acetyl-L-carnitine may modulate the immune response by increasing T-lymphocytes maturation and may downregulate pro-inflammatory cytokines in response to viruses, such as SARS-CoV-2. It may also disrupt the ACE2 signaling pathway and inhibit the production of reactive oxygen species (ROS).

Andrographolide (Andrographis)(Andrographis), an irreversible antagonist of NF-κB, has anti-inflammatory and anti-platelet aggregation activities and potential antineoplastic.

Hemin (Hemin chloride) is a chlorinated iron-containing porphyrin, a heme oxygenase (HO)-1 inducer. Hemin has therapeutic activity in porphyrias by reducing heme deficiency in patients, thereby inhibiting δ-aminolevulinic acid synthetase activity through biochemical feedback.

Silymarin (Silybin B) (Silybin B) is a polyphenolic flavonoid that extracts from the milk thistle or seeds of Silybum marianum. It is used in the prevention and treatment of liver diseases.

2-Hydroxycinnamic acid is a natural product isolated from Angraecum fragrans, has photooxidant activity.

Scutellarein (6-Hydroxyapigenin) reduces inflammatory responses by inhibiting Src kinase activity.

Dihydrotanshinone I (DHTS) is a natural compound extracted from Salvia miltiorrhiza Bunge used for treating of cardiovascular diseases.

Punicalagin is a major ellagitannin found in pomegranates that is reported to produce antioxidant, anti-inflammatory, and anticancer effects. It has been shown to prevent high-fat diet-induced obesity-associated accumulation of cardiac triglyceride and ch

Gedunin is an important limonoid present in several genera of the Meliaceae family, mainly in seeds. Gedunin is an Hsp90 inhibitor, and inhibits ovarian cancer cell proliferation.

4'-O-Methylbavachalcone (O-Methylbroussochalcone B) is isolated from Psoralea corylifolia, inhibits severe acute respiratory syndrome coronavirus (SARS-CoV) papain-like protease (PLpro) activity (IC50: 10.1 μM).

1. Arteannuin B has potent antimalarial activity.

Schisantherin E is a natural lignan isolated from Schisandra chinensis. Schisandra chinensis has antioxidant, hepatoprotective, sedative, anticancer, anti-SARS and anti-inflammatory activities.

Kansuinine B inhibits Stat3 activation induced by IL-6. Kansuinine B exhibits anti-viral activity and could be used in COVID-19 research.
