Antipyrine is an analgesic and antipyretic that has been given by mouth and as ear drops. It is often used in testing the effects of other drugs or diseases on drug-metabolizing enzymes in the liver. It inhibits cyclooxygenases and shows little anti-inflammatory activity. Like many old and approved substances after almost 100 years of use, antipyrine has been associated with some serious side effects, namely agranulocytosis and shock reactions.

Ethyl Methoxycinnamate (EPMC , Ethyl-p-methoxycinnamate) is a major constituent of Kaempferia galanga. with nematicidal, mosquito repellent, anti-neoplastic and anti-microbial activity. In preclinical studies Ethyl Methoxycinnamate shows marked larvicidal, antifungal and anti-inflammatory activities as well as inhibitory activity on susceptible and multi-drug resistant (MDR) clinical M. tuberculosis strains isolated from tuberculosis patients as well. In an in vitro anti-inflammatory mechanistic study, Ethyl Methoxycinnamate was found to inhibit both COX-1 and COX-2.

Fulvic acid is primarily studied for its effects on plants and soil. Fulvic acid is an organic and natural electrolyte. Depending on the situation, Fulvic acid can act as an electron donor or acceptor and an oxidizer or reducer. Fulvic acid has exhibited the ability to enhance the availability and adsorption of nutrients as well as prolong their time of residence. In the chick animal model Fulvic acid disturbed the processing of procollagen II in articular cartilage. Fulvic acid has being shown to attenuate homocysteine-induced cyclooxygenase-2 expression in human monocytes. Fulvic acid, the main active principle of Shilajit (a natural substance found mainly in the Himalayas), blocks tau self-aggregation, opening an avenue toward the study of Alzheimer's therapy. People take fulvic acid by mouth for brain disorders such as Alzheimer’s disease, as well as respiratory tract infections, cancer, fatigue, heavy metal toxicity, and preventing a condition in which the body tissues do not receive enough oxygen (hypoxia).

Wogonin is an O-methylated flavone compound isolated from Scutellaria baicalensis. Wogonin is an a positive allosteric modulator of benzodiazepine site of the GABAA ion channel, and displays anxiolytic properties in animal models. It possesses anti-tumor effect in models of osteosarcoma and lung cancer. Hepatoprotective action of wogonin was demonstrated in the mouse model of alcoholic liver disease and in a model of nonalcoholic fatty liver disease, where it was shown that wogonin upregulates PPAR-gamma and PPARalpha respectively. Wogonin possess chondroprotective action which was demonstrated in models of osteoarthritis.

Harpagoside is an anti-inflammatory small molecule natural product originally isolated from the Harpagophytum procumbens (Devil's Claw) root, but can be isolated from other plants such as Crophularia ningpoensis Hemsl (Figwort). Treatment of HepG2 cells with Harpagoside demonstrated suppression of NF-κB nuclear translocation and degradation of IκB-α, blocking NF-κB activation. Multiple anti-inflammatory cellular effects were correlated with this blockade, as Harpagoside was observed to inhibit the expression of inflammation-mediating enzymes cyclooxygenase-2 (COX-2) and inducible nitric oxide synthase (iNOS), and to reduce lipopolysaccharide-induced mRNA levels. The suppression of NF-κB activation is indicated as the mechanism beneath the anti-inflammatory effects of Harpagoside. Harpagoside is widely used as a folk remedy to treat rheumatic complaints.

Propyphenazone is a pyrazolone derivative with anti-inflammatory, analgesic and antipyretic activity. The coupling of propyphenazone with other widely used acidic NSAIDs such as ketoprofen, ibuprofen, and diclofenac produced mutual prodrugs with synergistic analgesic effects. It was introduced for the treatment of different types of pain and fever and rheumatic disorders. Propyphenazone structurally relates to aminophenazone it has been associated with severe blood dyscrasias.

1-(4-hydroxy-3-methoxyphenyl)decan-3-one (Paradol, 6-paradol ), a major constituent of A. melegueta seeds, exhibited potent proliferative and ossification characteristics in bone cells. It enhanced alkaline phosphatase activity and vitamin D content and decreased the osteoporotic marker acid phosphatase. Paradol enhanced the expression of osteocyte and osteoblast-related genes and inhibited osteoclast and RUNX suppressor genes. Paradols are unsaturated ketones produced by biotransformation of shogaols in gingers. Among them, 6-paradol has been investigated as a new drug candidate due to its anti-inflammatory, apoptotic, and neuroprotective activities. 6-paradol exhibited a significant glucose-lowering effect and decreased body weight. 6-paradol possesses good anti-hyperglycemic activity, therefore it may serve as a novel target for the development of anti-obesity and anti-hyperglycemic functional food. 6-paradol effectively protects brain after cerebral ischemia, likely by attenuating neuroinflammation in microglia, suggesting it as a potential therapeutic agent to treat cerebral ischemia.

L-Theanine is a relaxing and nondietary amino acid found pretty much exclusively in teas from Camellia sinensis (alongside green tea catechins and caffeine) and is known to promote relaxation without sedation. It appears to be effective at this as well as reducing stress at standard dosages. L-theanine was discovered as a constituent of green tea in 1949 and was approved in Japan in 1964 for unlimited use in all foods, including chocolates, soft drinks, and herb teas, except infant foods. It also provides a unique umami (brothy or savory) taste and flavor to green tea infusion. L-theanine may help relieve stress by inducing a relaxing effect without drowsiness and may also possess immunologic attributes. Theanine may also have effects on the cardiovascular system and play a preventative role in cancer; however, limited clinical information is available to support these claims. L-Theanine and its positive effects on cognitive performance is one of its most important functions. Because of chemical structure of L-Theanine similar to glutamate it can act as a neurotransmitter related to memory. In a study made on rats, it was found out that L-Theanine modulated the serotonin and dopamine levels and increased learning skills with memory. In addition, it is stated that L-Theanine increases neuro - throphine mRNA level by activating its neuro - transmitter inhibiting system and supports the central nervous system that helps the development of brain functions. L-Theanine had a positive effect on memory and had positive effects on the treatment and prevention of Alzheimer. Theanine is an antagonist of the NMDA receptors (albeit with fairly weak efficacy) and can inhibit synaptic release of glutamate via blocking the transporter competitively. Theanine may also reduce glutamate levels, but this is also a fairly weak mechanism requiring a high concentration of theanine.

Madecassoside is a triterpenoid compound found in Centella asiatica (Gotu kola), a medicinal herb used in traditional Chinese medicine (TCM), Ayurvedic medicine, and traditional African medicine. Madecassoside has a wide range of reported biological activities including, anti-inflammatory, wound healing, and anti-oxidant activities. It has been reported to suppress LPS-induced TNF-alpha production via inhibition of ERK, p38, and NF-kappaB activity. Madecassoside, a triterpenoid derivative isolated from Centella asiatica, exhibits anti-inflammatory and antioxidant activities. Madecassoside significantly reduced brain infarct area, resolved neurological deficit, and ameliorated neuronal apoptosis. It also significantly reduced the levels of malondialdehyde and nitric oxide, and augmented the antioxidant activity in rats subjected to cerebral I/R. Moreover, the levels of pro-inflammatory cytokines and NF-κB p65 significantly reduced after madecassoside treatment. Madecassoside is neuroprotective and may be useful in reducing the damage caused by stroke. Madecassoside has being shown to inhibits melanin synthesis by blocking ultraviolet-induced inflammation.
