This chemical is also a substrate for enzymatic reactions, such as amination reactions, condensation reactions, and electrophilic addition reactions. The compound has been shown to inhibit energy metabolism in swiss-webster mice by blocking the conversion of glycogen into glucose in liver cells.</p>

<p>3,5-Dichlorophenyl isothiocyanate is an electrophile that has been shown to degrade polyethylene terephthalate (PET) and polyisoprene. It is also resistant to high temperatures and may be used for the treatment of bacterial infections. 3,5-Dichlorophenyl isothiocyanate has antibacterial properties and can inhibit the growth of bacteria by binding to fatty acids or dione. 3,5-Dichlorophenyl isothiocyanate has also been shown to have antifungal properties against Candida albicans and Trichophyton rubrum.</p>

<p>2,6-Dichlorophenylisothiocyanate is a chloride that is used to treat tuberculosis. It is a prodrug that is hydrolyzed in the body to form 2-amino-3-chloropyrazine and imidazoles which are active against Mycobacterium tuberculosis and Mycobacterium avium complex. 2,6-Dichlorophenylisothiocyanate can be administered orally as well as intravenously. It has been shown to have tuberculostatic activity in animal models of experimental tuberculosis. The mechanism of action for this drug is not fully understood, but it may be due to its ability to inhibit protein synthesis by binding to bacterial ribosomes.</p>

<p>2,4-Dichlorophenyl isothiocyanate (2,4-DCPI) is a benzimidazole derivative that binds to the benzimidazole-binding site of the α1 subunit of the glutamate receptor. 2,4-DCPI inhibits tumor cell proliferation by binding to a specific region of the alpha 1 subunit of the glutamate receptor. This binding prevents glutamate from activating its receptor and initiating intracellular signaling pathways that promote tumor cell growth. 2,4-DCPI has been shown to inhibit the proliferation of human cancer cells in culture with significant inhibitory activities against mda-mb231 cells. It also inhibits angiogenesis and metastasis by inhibiting vascular endothelial growth factor (VEGF) production. The molecule was observed to have an effect on chloride secretion in rats, which may be related to its pharmacokinetic properties.</p>

<p>N-Methylethane-1-sulfonamide is a nonsteroidal antiestrogen that has been shown to inhibit the growth of breast cancer cells in vitro. It has also been shown to have a protective effect on cardiac tissues. N-Methylethane-1-sulfonamide is highly selective for estrogen receptors, and it is believed that this selectivity may be due to its ability to inhibit the enzyme 17β-hydroxysteroid dehydrogenase, which converts estrone into estradiol. The drug has been shown to increase the amount of progesterone in rats with induced ovarian cysts and decrease the number of oocytes released by female Xenopus laevis frogs. It also inhibits gene expression by binding to DNA at specific sites, thereby blocking transcription or translation. This drug is not active against bronchial asthma or cardiac arrhythmia in rodents; however, it can cause enantioselective inhibition of cardiac contractility</p>
