Solanidine
Solanidine is a steroid alkaloid fundamental parent, a 3beta-hydroxy-Delta(5)-steroid and a solanid-5-en-3-ol. It has a role as a plant metabolite and a toxin. It is a conjugate base of a solanidine(1+). Solanidine is a natural product found in Fritillaria delavayi, Fritillaria tortifolia, and other organisms with data available. Alkaloid from potato (Solanum tuberosum). Glycosides, (especies Solanines and chaconine) are trace toxic constits. of potato tubers (especies greened tubers), and interbreeding of potatoes with wild strains may increase their concn. or introduce other more toxic, solanidine glycosides Solanidine is a steroidal alkaloid, and its glycosides have been reported to have caused poisoning in man and animals. Solanidine is present in sera of healthy individuals and in amounts dependent on their dietary potato consumption. (PMID: 4007882). Solanidine is a cholestane alkaloid isolated from several potato species including Solanum demissum, Solanum acaule, and Solanum tuberosum. Solanidine can inhibit proliferation and exhibit obvious antitumor effect[1].

Tomatidine
Tomatidine is the aglycone derivative of tomatine. Tomatidine belongs to the chemical family known as Spirosolanes and Derivatives. These are steroidal alkaloids whose structure contains a spirosolane skeleton. Tomatine (the glycosylated form of tomatidine) is a mildly toxic glycoalkaloid or glycospirosolane found in the stems and leaves of tomato plants as well as in the fruit of unripened (green) tomatoes (up to 500 mg/kg). Red, ripe tomatoes have somewhat reduced amounts of tomatine and tomatidine. Both tomatine and tomatidine possess antimicrobial, antifungal and antiviral properties. Tomatidine has been shown to exhibit anti-virulence activity against normal strains of Staphylococcus aureus as well as the ability to potentiate the effect of aminoglycoside antibiotics (PMID: 24877760). Recent studies have shown that tomatidine stimulates mTORC1 signaling and anabolism, leading to accumulation of protein and mitochondria, and ultimately, cell growth. Furthermore, in mice, tomatidine has been shown to increase skeletal muscle mTORC1 signaling, reduce skeletal muscle atrophy, enhance recovery from skeletal muscle atrophy, stimulate skeletal muscle hypertrophy, and increase strength and exercise capacity (PMID: 24719321). Tomatidine has also been shown to significantly inhibit cholesterol ester accumulation induced by acetylated LDL in human monocyte-derived macrophages in a dose-dependent manner. Tomatidine also inhibits cholesterol ester formation in Chinese hamster ovary cells overexpressing acyl-CoA:cholesterol acyl-transferase (ACAT)-1 or ACAT-2, suggesting that tomatidine suppresses both ACAT-1 and ACAT-2 activities. The oral administration of tomatidine to apoE-deficient mice significantly reduces levels of serum cholesterol, LDL-cholesterol, and the size of atherosclerotic lesions (PMID: 22224814). Alkaloid from Lycopersicon esculentum (tomato). Tomatidine is found in garden tomato, garden tomato (variety), and potato. Tomatidine acts as an anti-inflammatory agent by blocking NF-κB and JNK signaling[1]. Tomatidine activates autophagy either in mammal cells or C elegans[2].

Tomatine
Tomatine is a mildly toxic glycoalkaloid or glycospirosolane (steroidal alkaloids whose structure contains a spirosolane skeleton) found in the stems and leaves of tomato plants as well as in the fruit of unripened (green) tomatoes (up to 500 mg/kg). Red, ripe tomatoes have somewhat reduced amounts of tomatine. A toxic dose of tomatine for an adult human would appear to require the consumption of at least 500 g of tomato leaves in one sitting (“Toxic Plants of North America” (Iowa State University Press, 2001)). Tomatine is known to have fungicidal and antimicrobial properties and is likely produced by tomato plants as a defense against bacteria, fungi, viruses, and insects (PMID: 19514731). Some microbes produce an enzyme called tomatinase which can degrade tomatine, rendering it ineffective as an antimicrobial (PMID: 18835993).Tomatine has historically been used as a reagent in analytical chemistry for precipitating cholesterol from solution (PMID: 4362143). When lab animals ingest tomatine, essentially all of it passes through the animal unabsorbed. Tomatine apparently binds to cholesterol in the digestive tract, and the largely insoluble combination is excreted — ridding the body of both the alkaloid and cholesterol. Experiments with hamsters have shown that both tomatine-rich green tomatoes and purified tomatine can substantially lower the levels of undesirable LDL cholesterol while maintaining normal levels of HDL (PMID: 10942315). Experiments with high-tomatine green tomato extracts were recently shown to strongly inhibit the growth of a number of human cancer cell lines including breast (MCF-7), colon (HT-29), gastric (AGS), and hepatoma (liver) (HepG2), as well as normal human liver cells (PMID: 19514731). Other studies have found that purified tomatine is an outstanding immunoadjuvant capable of stimulating potent antigen-specific humoral and cellular immune responses that contribute to protection against malaria, Francisella tularensis and regression of experimental tumors (PMID: 15193398). Tomatine is a mildly toxic glycoalkaloid or glycospirosolane (steroidal alkaloids whose structure contains a spirosolane skeleton) found in the stems and leaves of tomato plants as well as in the fruit of unripened (green) tomatoes (up to 500 mg/kg).

beta-2-Chaconine
Beta-2-chaconine is a member of the class of compounds known as steroidal saponins. Steroidal saponins are saponins in which the aglycone moiety is a steroid. The steroidal aglycone is usually a spirostane, furostane, spirosolane, solanidane, or curcubitacin derivative. Beta-2-chaconine is practically insoluble (in water) and a very weakly acidic compound (based on its pKa). Beta-2-chaconine can be found in potato, which makes beta-2-chaconine a potential biomarker for the consumption of this food product.
