Zeatin is a cytokinin plant growth factor, which has gerontomodulatory, youth preserving and anti-aging effects on serially passaged human adult skin fibroblasts undergoing aging in vitro.

Cypermethrin is a synthetic, pyrethroid insecticide that has high insecticidal activity, low avian and mammalian toxicity. Cypermethrin works by quickly affecting the insect’s central nervous system. The major target site of cypermethrin is the sodium channel of the nerve membrane. A sodium channel exposed to cypermethrin can remain open much longer, even up to several seconds. It is used to control many pests including lepidopterous pests of cotton, fruit, and vegetable crops. In veterinary, it is applied topically for the control of ectoparasites such as ticks, fleas, lice and blowflies.

Nitenpyram is a neonicotinoid, a neurotoxin that blocks neural messages and used in agriculture and veterinary medicine to kill external parasites of pets. Imidacloprid act as agonists at the insect nicotinic acetylcholine receptor (nAChR). The botanical insecticide nicotine acts at the same target without the neonicotinoid level of effectiveness or safety. Fundamental differences between the nAChRs of insects and mammals confer remarkable selectivity for the neonicotinoids. Whereas ionized nicotine binds at an anionic subsite in the mammalian nAChR, the negatively tipped ("magic" nitro or cyano) neonicotinoids interact with a proposed unique subsite consisting of cationic amino acid residue(s) in the insect nAChR. Nitenpyram was introduced into the United States in 1994 as a veterinary flea control treatment, structural pest and crop insecticide, and seed treatment. It has been used orally in dogs, cats, and some wildlife species for over 10 years. After ingestion, it begins killing adult fleas within 30 minutes, and effects continue for up to 48 hours. Though nitenpyram is used to kill adult fleas quickly on an infected animal, it does not kill insect eggs and has no long-term activity. Thus, it is not effective as a long-term flea preventative; however, it can be repeatedly applied over the course of several days to eradicate a single instance of infestation. Nitenpyram can be combined with a longer-term flea preventative like fipronil or lufenuron to prevent reinfestation. Neonicotinoids for veterinary use are considered to have a low order of toxicity for domestic animals and there are no reports of nitenpyram intoxication.

Hydroprene is a synthetic version of the insect hormone that regulates growth and development. Hydroprene can be considered as an alternative to conventional insecticides because of its specific activity against immature insect stages, low persistence in the environment, and virtually non-toxic effects on mammals. Hydroprene products are used on a variety of indoor sites including homes, offices, warehouses, restaurants, hospitals, and greenhouses.

Amidoflumet is a trifluoromethanesulfonanilide compound with high house dust miticidal activity which was discovered by Sumitomo Chemical, and was registered in Japan in 2004. House dust mites and their products are known to be major household allergens to children and the elderly, and they cause asthma and atopic dermatitis. Amidoflumet shows high lethal activity against common house dust mites.

Famphur is an insecticide and antihelmenthic. Famphur is approved in cattle as a pour-on (NADA 34-697; 21 CFR 524.900) and as medicated feed (NADA 34-266; 21 CFR 558.254). It is a component of the FDA-approved TRAMISOL X-TRA Combination Paste, used for the treatment of cattle infected with the following parasites: Stomach worms (Haemonchus, Trichostrongylus, Ostertagia), intestinal worms (Trichostrongylus, Cooperia, Nematodirus, Bunostomum, Oesophagostomum), lungworms (Dictyocaulus), cattle grubs (Hypoderma), biting lice (Bovicola), and sucking lice (Linognathus, Solenoptes). Famphur is a cholinesterase-inhibiting drug.

Cythioate is an organothiophosphate chemical used as an insecticide and anthelmintic. Cythioate is a cholinesterase inhibitor. Marketed under the trade names Cyflee and Proban, Cythioate is indicated for the control of ticks, fleas, and demodectic mange in dogs, and fleas in cats.

Pyrethrins are natural insecticides derived from chrysanthemum flowers containing a mixture of six components: pyrethrin I, cinerin I, jasmolin I, pyrethrin II, cinerin II, and jasmolin II. Pyrethrin I is one of the two pyrethrins, natural organic compounds with potent insecticidal activity. It is an ester of ( )-trans-chrysanthemic acid with (S)-(Z)-pyrethrolone. Pyrethrins induce a toxic effect in insects when they penetrate the cuticle and reach the nervous system. Pyrethrins bind to sodium channels that occur along the length of nerve cells. Sodium channels are responsible for nerve signal transmission along the length of the nerve cell by permitting the flux of sodium ions. When pyrethrins bind to sodium channels, normal function of the channels is obstructed thereby resulting in hyperexcitation of the nerve cell and, consequently, a loss of function of the nerve cell. The shutdown of the insect nervous system and death are most often the consequences of insect exposure to pyrethrins.

Clorfenvinfos (chlorfenvinphos) is an organophosphate insecticide, which is used to control insect pests on livestock, and to control household pests such as flies, fleas, and mites. Clorfenvinfos was sold under trade names including Birlane®, Dermaton®, Sapercon®, Steladone®, and Supona®. In 1991 all products containing clorfenvinfos were banned in the USA. Toxicity of clorfenvinfos is due to inhibition of acetylcholinesterase. Inhibition of cholinesterase activity results in the accumulation of acetylcholine at muscarinic and nicotinic receptors. This leads to continuous or excessive stimulation of cholinergic fibers in the post-ganglionic parasympathetic nerve endings, neuromuscular junctions of the skeletal muscles, resulting in hyperpolarization of nerve or muscle fibers and receptor desensitization until hydrolysis of the phosphorylated cholinesterase occurs. In some cases, a dealkylation and stabilization of the phosphorylated enzyme (“aging”) occur such that hydrolysis can no longer take place and the enzyme is irreversibly inhibited. In such cases, the return of acetylcholinesterase activity parallels the time required to resynthesize this enzyme.
