imatinib
Imatinib, sold under the brand names Gleevec and Glivec (both marketed worldwide by Novartis) among others, is an oral targeted therapy medication used to treat cancer. Imatinib is a small molecule inhibitor targeting multiple tyrosine kinases such as CSF1R, ABL, c-KIT, FLT3, and PDGFR-β. Specifically, it is used for chronic myelogenous leukemia (CML) and acute lymphocytic leukemia (ALL) that are Philadelphia chromosome–positive (Ph+), certain types of gastrointestinal stromal tumors (GIST), hypereosinophilic syndrome (HES), chronic eosinophilic leukemia (CEL), systemic mastocytosis, and myelo
cotinine
Cotinine is an alkaloid found in tobacco and is also the predominant metabolite of nicotine, typically used as a biomarker for exposure to tobacco smoke. Cotinine is currently being studied as a treatment for depression, post-traumatic stress disorder (PTSD), schizophrenia, Alzheimer's disease and Parkinson's disease. Cotinine was developed as an antidepressant as a fumaric acid salt, cotinine fumarate, to be sold under the brand name Scotine, but it was never marketed.

nikethamide
Nikethamide is a stimulant which mainly affects the respiratory cycle. Widely known by its former trade name of Coramine, it was used in the mid-twentieth century as a medical countermeasure against tranquilizer overdoses, before the advent of endotracheal intubation and positive-pressure lung expansion. It is no longer commonly considered to be of value for such purposes.

nilotinib
Nilotinib, sold under the brand name Tasigna among others, is an anti-cancer medication used to treat chronic myelogenous leukemia (CML) which has the Philadelphia chromosome. It may be used both in initial cases of chronic phase CML as well as in accelerated and chronic phase CML that has not responded to imatinib. It is taken by mouth.

It is one of three positional isomers of methylpyridine, whose structures vary according to where the methyl group is attached around the pyridine ring. This colorless liquid is a precursor to pyridine derivatives that have applications in the pharmaceutical and agricultural industries. Like pyridine, 3-methylpyridine is a colorless liquid with a strong odor and is classified as a weak base.

pyriminil
Pyrinuron (Pyriminil, Vacor) is a chemical compound formerly used as a rodenticide. Commercial distribution was voluntarily suspended in 1979 and it is not approved by the Environmental Protection Agency for use in the United States. If it is ingested by humans in high doses, it may selectively destroy insulin-producing beta cells in the pancreas causing type 1 diabetes. The neurodegeneration associated with Vacor is caused by its conversion to Vacor-mononucleotide (VMN) by NAMPT and VMN's subsequent activation of the NADase SARM1.
masitinib
Masitinib is a tyrosine-kinase inhibitor used in the treatment of mast cell tumours in animals, specifically dogs. Since its introduction in November 2008 it has been distributed under the commercial name Masivet. It has been available in Europe since the second part of 2009. Masitinib has been studied for several human conditions including melanoma, multiple myeloma, gastrointestinal cancer, pancreatic cancer, Alzheimer's disease, multiple sclerosis, rheumatoid arthritis, mastocytosis, amyotrophic lateral sclerosis, and COVID-19.
nemertelline
Nemertelline is a neurotoxic tetra-pyridine compound originally found in the marine ribbon worm Amphiporus angulatus. These worms produce a variety of toxins which are used both in hunting down prey and in defending themselves from predators. Interest in potential application of this compound as an antifouling agent for boats and other marine installations has led to attempts to produce it synthetically by convenient routes. This compound is highly toxic to crustaceans but not mammals and is similar to the plant alkaloid nicotelline in structure.
4-(N-nitrosomethylamino)-1-(3-pyridyl)-1-butanone
Nicotine-derived nitrosamine ketone (NNK) is one of the key tobacco-specific nitrosamines (TSNAs) derived from nicotine. It plays an important role in carcinogenesis. The conversion of nicotine to NNK entails opening of the pyrrolidine ring.

Commercial tobacco plants typically produce alkaloids at levels between 2% and 4% of total dry weight, with nicotine accounting for about 90% of the total alkaloid content, and the related compounds anatabine, nornicotine, and anabasine making up nearly all the rest. These compounds are thought to be biologically active, and part of plants' natural defense system against insects.

Aluminium nicotinate
chemical compound
pymetrozine
Pymetrozine is an insecticide in the pyridine-azomethine chemical class, primarily utilized for controlling homopteran pests, such as aphids and whiteflies, in agricultural settings. It selectively targets the nervous system of sap-feeding insects, causing them to cease feeding soon after ingestion. This unique mechanism limits impact on non-target beneficial insects. Pymetrozine has been extensively used on rice, potato and brassica crops as an alternative to organophosphorus pesticides.
ABT-202
ABT-202 is a drug developed by Abbott, which acts as an agonist at neural nicotinic acetylcholine receptors and has been researched for use as an analgesic, although it has not passed clinical trials.
rivanicline
Rivanicline (TC-2403, RJR-2403, (E)-metanicotine) is a drug which acts as a partial agonist at neural nicotinic acetylcholine receptors. It is subtype-selective, binding primarily to the α4β2 subtype. It has nootropic effects and was originally developed as a potential treatment for Alzheimer's disease, but a second action that was subsequently found was that it inhibits the production of Interleukin-8 and thus produces an antiinflammatory effect, and so it has also been developed as a potential treatment for ulcerative colitis. Rivanicline also has stimulant and analgesic actions which are th
3-bromopyridine
3-Bromopyridine is an aryl bromide and isomer of bromopyridine with the formula C5H4BrN. It is a colorless liquid that is mainly used as a building block in organic synthesis.

The other isomers are pyridine-2-carboxaldehyde and pyridine-4-carboxaldehyde. It is a colorless liquid that is routinely available commercially. It can be produced from nicotinonitrile. Alternatively, it arises by the aerobic oxidation of the corresponding alcohol.
