Aliphatic compounds and derivatives

1-Hexen-3-one is a carbonyl compound that has been shown to act as an estrogen receptor modulator. It has been isolated from the reaction product of hexene and formaldehyde, in which the intramolecular hydrogen is transferred to the carbon atom adjacent to the carbonyl group. 1-Hexen-3-one has been shown to induce muscle cell proliferation in vitro and inhibit liver microsomal protein synthesis in vivo. The 1-hexen-3-one can be prepared by reacting hexene with formaldehyde. The yield of this reaction is about 80%.
2 HCHO + C6H12 → C6H14O + 2 HCOOH

5-Bromo-1-pentene (5BP) is an antitumoral drug that has potent inhibitory activity against the t-cell leukemia cell line and other tumor cells. 5BP is an organoborane ester with a bromine atom at the 1-position. It is synthesized by reacting trifluoroacetic acid with a hydrohalic acid such as hydrochloric acid, or with a metal halide such as sodium carbonate, followed by reaction with dimethyl formamide and n-dimethylformamide. The 5BP molecule has a coordination geometry of octahedral and its structure consists of three hydrogen atoms, two methyl groups, one hydroxyl group, and one unsaturated alkyl group. The mechanism of action of 5BP is still unclear. The inhibition of protein synthesis may be due to the steric hindrance caused by the bulky bromine atom at the 1 position on the benzene ring.

2-Oxa-6-azaspiro[3.4]octane is an epidermal growth factor (EGF) inhibitor that has shown inhibitory activities against a number of different EGFR-related cell lines, including parental and mutant cell lines. This drug has been shown to inhibit the proliferation of cancer cells in vitro by binding to the epidermal growth receptor (EGFR). 2-Oxa-6-azaspiro[3.4]octane also inhibits the activity of tyrosine kinases and factor receptors, which are involved in the development of cancer cells. It is a potent inhibitor of TK1 and TK2 tyrosine kinases, and is more potent than piperazine or morpholine, which are other EGF inhibitors.
