Ambroxol (NA-872) is a secretolytic agent used in the treatment of respiratory diseases associated with viscid or excessive mucus. It is the active ingredient of Mucosolvan, Lasolvan or Mucoangin. The substance is a mucoactive drug with several properties including secretolytic and secretomotoric actions that restore the physiological clearance mechanisms of the respiratory tract which play an important role in the body's natural defense mechanisms. It stimulates synthesis and release of surfactant by type II pneumocytes. Surfactants act as an anti-glue factor by reducing the adhesion of mucus to the bronchial wall, in improving its transport and in providing protection against infection and irritating agents.

Praziquantel (Droncit) increases the permeability of the tegument of susceptible worms, resulting in an influx and increase in intra-tegumental calcium leading to rapid contractions and paralysis of the worm's musculature through a subsequent increase in levels of calcium in the sarcoplasmic reticulum. Praziquantel is a pyrazinoisoquinoline derivative with anthelminthic property. In addition, vacuolization of the tegumental syncytium and blebbing results in tegument disintegration, leads to antigen exposure and elicit host defense responses to the worm.

Rebamipide (OPC12759) is a quinolinone derivative with anti-ulcer and anti-inflammatory activities. Rebamipide induces cyclooxygenase 2 (COX2) synthesis which results in an increase in endogenous prostaglandin synthesis in the gastric mucosa. This agent also inhibits H. pylori-induced production of tumor necrosis factor (TNF) alpha and subsequent inflammation of the gastric mucosa. In addition, rebamipide scavenges oxygen-derived free radicals that potentially cause mucosal injury, and stimulates prostaglandin EP4 receptor gene expression followed by mucous secretion, thereby enhancing the gastric mucosal defense.

1,4-Diaminobutane Dihydrochloride (1,4-butanediamine Dihydrochloride) has antidepressant and analgesic effects. It regulates plant defense against environmental stresses by directly killing fungi and inducing resistance mechanisms, enhancing post-harvest mango fruit resistance to Colletotrichum gloeosporioides.

1. Linalool (Linalol), a natural compound of the essential oils, has been shown to have antinociceptive, antimicrobial, and anti-inflammatory properties. 2. Linalool was protected against LPS/GalN-induced liver injury through induction of antioxidant defense via Nrf2 activating and reduction inflammatory response via NF-κB inhibition. 3. Linalool biosynthesis and accumulation might be involved in plant defense against bacterial and fungal pathogens and be associated with field resistance to citrus canker. 4. Linalool significantly increased the expression of antioxidant enzymes regulated by Nrf-2 and diminished lung tissue levels of several pro-inflammatory cytokines, including tumor necrosis factor α (TNF-α) and interleukin (IL)-6.

L-Allothreonine (L-allo-Threonine) is an essential amino acid in humans. L-Allothreonine is abundant in human plasma, particularly in newborns. Severe deficiency of threonine causes neurological dysfunction and lameness in experimental animals. L-Allothreonine is an immunostimulant which promotes the growth of thymus gland. L-Allothreonine also can probably promote cell immune defense function. L-Allothreonine is highly concentrated in meat products, cottage cheese, and wheat germ.

Methyl jasmonate ((-)-Methyl jasmonate) is a hormone involved in plant signaling, inducing oxidative stress and accumulation of secondary metabolites in plant cells and organ cultures, and regulating the biosynthesis of other plant hormones. Methyl jasmonate induces plant defense responses against Andean lupin insects. Methyl jasmonate has anti-inflammatory activity.

cis-​Jasmone is a natural product isolated from the volatile portion of the oil from jasmine flowers,as an insect semiochemical and in plant defense

Dusquetide aceate is an innate immune defense regulator against damage-associated molecular patterns and pathogen-associated molecular patterns. Dusquetide aceate shows anti-inflammation and antibacterial activities.

Neolinustatin a naturally occurring cyanoglycoside, is able to gradually produce HCN through enzymatic reactions as part of the plant's defense system against insects and pathogens.

Jasmonic acid (JA) is a phytohormone and plant growth regulator involved in plant defense and growth and development.Jasmonic acid plays an important role in signaling, inducing the MAP kinase cascade pathway and calcium channels.

Double carbene can be used for the study of schizophrenia and alcoholism. It can block dopamine receptors in various parts of the brain and prevent the reduction of conditioned defense reflexes caused by the stimulation of the mid-brain part of the networ

Dusquetide TFA is a kind of innate defense regulator (IDR).Dusquetide TFA has been shown to be active in reducing inflammation and increasing clearance of bacterial infections.Dusquetide TFA regulates innate immune responses to PAMPs and DAMPs in combinat

Dusquetide is a first-in-class innate defense regulator. Dusquetide displays activity in both reducing inflammation and increasing the clearance of bacterial infection.

Acibenzolar-S-methyl is a plant resistance inducer and salicylic acid analogue that enhances plant disease resistance by activating the production of pathogen-associated proteins in the intercellular spaces of plants, thereby inducing systemic acquired resistance.

Aspinonene is a bioactive compound that regulates plant growth and defense mechanisms. It participates in the biochemical signaling pathways within plants, affecting various physiological responses such as growth, defense, and adaptation to environmental stresses.

Sesaminol is an orally active activator of the Nrf2-ARE signaling pathway, promoting the nuclear translocation of Nrf2 and boosting the expression of NQO1 to enhance cellular defense against oxidative stress. It inhibits 6-OHDA-induced ROS production and apoptosis in SH-SY5Y cells. Sesaminol also provides neuroprotective effects against Rotenone-induced Parkinson's disease.

CRX 527 is a TLR4 ligand and serves as an adjuvant for peptide cancer vaccines, enhancing anti-tumor immune responses. CRX 527 also induces hematopoietic stem cell (HSC) differentiation, increasing the proportion and number of LSK cells, and promotes their differentiation into macrophages. This activation bolsters immune defense and protects intestinal epithelium from radiation damage.

Benzohydroxamic acid (BHA) is a chitin deacetylase (CDA) inhibitor with notable antifungal properties. It displays Ki values of 8.31 μM against Verticillium dahliae CDA and 9.83 μM against Puccinia striiformis f. sp. tritici CDA. BHA can restore the defense responses in infected host plants by upregulating the expression of defense-related genes, thereby reducing fungal growth and proliferation within the plants. It is applicable in the research of agricultural fungal diseases, such as cotton wilt and wheat stripe rust, caused by pathogens like Verticillium dahliae and Puccinia striiformis.

Herbicidal agent 4 (compound V-2) is an oxidative herbicide. It can upregulate defense genes and increase jasmonic acid levels, suggesting it may also function as an immune activator.

(±)-Jasmonic-L-isoleucine ((±)-JA-L-Ile) is a conjugate of the plant hormone jasmonic acid and the amino acid isoleucine, representing the active form in the jasmonic acid signaling pathway. (±)-Jasmonic-L-isoleucine regulates various biological processes in plants, including defense responses, growth and development, and stress adaptation.

Ferroptosisinducer-8 is a ferroptosis (iron-dependent cell death) inducer with high selectivity against other cell death pathways. It induces ferroptosis by affecting ACSL4, GPX4, and FTH1, disrupting intracellular iron homeostasis and the GSH/GPX4 antioxidant defense system, leading to the accumulation of lipid peroxides. Ferroptosisinducer-8 also stimulates ROS production and can inhibit tumor growth, making it useful for research in triple-negative breast cancer (TNBC).
