Cinnamic acid is a polyphenol found in cinnamon oil and used in commercial flavorings. Recent studies have shown the pharmacological properties of cinnamic acid and its derivatives, including hepatoprotective, anti-oxidant, and anti-diabetic activities. In preclinical studies cinnamic acid demonstrated to be a promising candidate for the treatment ob obesity and diabetes. The mechanism of action of cinnamic acid in obesity is explained by its ability to inhibit lipases and ACE (angiotensin-converting enzyme). However, there are several hypotesis regarding the effect of cinnamic acid in diabetes: cinnamic acid enhances glucose-induced insulin secretion, prevents palmitic acid-induced lipotoxicity, inhibits palmitic acid-induced alteration of lipogenic gene and protein expression (AMPK, SREBP-1c, FAS, ACC), inhibits DPP IV, exhibits an additive effect on the uptake of glucose, stimulates adiponectin secretion, etc.

Menthyl 2-hydroxypropyl carbonate is a methyl ester used as a flavoring and cooling agent. It provides a prolonged physiological cooling sensation to the skin or mucus membrane. It is used in gum or confections.

Propylene Glycol Ricinoleate is an ester of propylene glycol and ricinoleic acid. Clear, pale, moderately viscous liquid emollient derived from castor oil. Because it forms occlusive barriers, it reduces transepidermal water loss, and also hydrates the skin through humectancy via hydrogen bonding between water and the material’s hydroxyl groups, being able to attract and bind water from the atmosphere and lower layers of the epidermis and dermis. It can be used in color cosmetics, AP/DEO, lipsticks, sun care, lip balms, shave products, creamy cleansers, creams and lotions, massage oils, lip treatments.

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.
