Tyramine Derivatives as Versatile Pharmacophores With Potent Biological Properties: Sex Hormone–Binding Globulin Inhibition, Colon Cancer Antimigration, and Antimicrobial Activity.

Guided by the idea that the presence of a heterocyclic aromatic core and tyramine moiety, under the umbrella of a single molecular scaffold could bring interesting biological properties, herein we present synthesis, characterization, with two crystal structures reported, and biological evaluation of some tyramine derivates. Cytotoxic and antimigratory potential was addressed by using a colorectal cancer cell line as a model system. Although possessing no cytotoxic effects, two compounds have shown strong antimigratory potential in low doses, with no effect on healthy MRC‐5 cells. Evaluation of their antimicrobial activities suggested prominent antimicrobial activity, where Compound 4 outperformed streptomycin against Escherichia coli and Proteus mirabilis. Hormone‐dependent types of cancer, such as prostate, ovary, and breast, are highly dependent on human sex hormone–binding globulin (SHBG) blood levels. A molecular docking study has shown that 1 has high affinity to bind and therefore compete with natural steroids for the SHBG steroid‐binding site. DNA‐binding study have shown that 4 interacts with CT‐DNA in a groove‐binding mode. In silico ADME/T study revealed that all compounds have suitable physicochemical properties for oral bioavailability and druglikeness, while toxicity tests for 1, 4, and 6 suggested potential for mutagenicity (4, 6), hepatotoxicity (6), and skin sensation (1).
