5-Methylindole-2-carboxylic acid (5MICA) is a synthetic compound that has been shown to be cytotoxic in vitro. It has been shown to inhibit the growth of multiple cancer cell lines, including hepatoma cells, and is currently being studied as a potential anticancer drug. 5MICA inhibits the synthesis of protein and RNA by binding to the ribosome. This inhibition leads to cell death by apoptosis. 5MICA also exhibits an antimicrobial effect against opportunistic fungal pathogens such as Candida albicans, Aspergillus fumigatus, and Cryptococcus neoformans. The mechanism for this inhibition is unknown but may involve inhibition of protein synthesis or other cellular processes.

3-Amino-5-nitroindazole is an anticancer drug that inhibits the growth of cancer cells. It has been shown to inhibit the growth of cancer cells by blocking the synthesis and repair of DNA, leading to cell death. 3-Amino-5-nitroindazole also blocks the production of new proteins, which are needed for cell division. This drug also acts on pathways that are important for tumor development and progression, such as signaling pathways and transcription factors. This compound has been shown to be selective against human squamous cell carcinoma cells and has been studied in combination with other anticancer drugs in clinical trials.

4-Aminoindole is a heterocycle with a carboxy group and four nitrogen atoms. It can be synthesized by reacting hydrochloric acid with nitrobenzene. 4-Aminoindole has shown potential as a drug target, which may be due to its ability to inhibit the enzyme carboxamidase. The compound is also acidic in water, making it an ideal candidate for use as an acid catalyst. Electropolymerization of 4-aminoindole has been achieved using Pt electrodes in the presence of an acidic environment. This reaction results in the formation of functional groups on the metal surface that are not found in most other electropolymerization reactions.

Indole-3-acetamide is an organic compound that is a component of the natural amino acid tryptophan. Indole-3-acetamide has been shown to be a potential anti-cancer drug. It inhibits prostate cancer cells and wild-type strains by inhibiting fatty acid synthase, which is an enzyme that catalyzes the synthesis of fatty acids. Indole-3-acetamide is also able to increase the production of monoclonal antibodies in mice with antigenic stimulation.

Psoralen is a naturally occurring furocoumarin compound, which is derived from various plants, including those in the Apiaceae family, such as parsley and celery. Its mode of action involves intercalating into DNA and forming covalent cross-links when activated by ultraviolet A (UVA) light. This photoreactivity enables it to modify the biological activity of nucleic acids, making it a valuable tool in both therapeutic and experimental settings.

(S)-(-)-3-Aminoquinuclidine 2HCl is a cholinergic agonist that has been shown to be effective in inducing the release of acetylcholine from brain synaptosomes. This drug binds to the nicotinic acetylcholine receptor (nAChR) and inhibits the action of the enzyme acetylcholinesterase, thereby increasing the concentration of acetylcholine in the synaptic cleft. The drug is also able to cross the blood-brain barrier and bind to receptors on neurons. It has been shown that this drug can be used as an imaging agent for molecular magnetic resonance tomography (MRT), with high sensitivity and specificity.
