Tyrian purple is a pigment made from the mucus of several species of Murex snail. Production of Tyrian purple for use as a fabric dye began as early as 1200 BC by the Phoenicians, and was continued by the Greeks and Romans until 1453 AD, with the fall of Constantinople.
One of the dye's main chemical ingredients is red dibromo-indigotin, the main component of tyrian purple or tekhelet. [4] The dye will turn indigo blue, similar to the color of blue jeans, if exposed to sunlight before the dye sets. Subspecies. Hexaplex trunculus trunculus (Linnaeus, 1758)

The analysis identified it as an “incredibly rare” lump of Tyrian purple dye, also known as imperial purple, the company said in a May 3 news release. “For millennia, Tyrian Purple was the ...
Costly and labor-intensive dyes Tyrian purple (or "royal purple") and tekhelet were historically made by the ancient Phoenicians and Jews respectively, using mucus from the hypobranchial gland of two species commonly referred to as "murex", Murex brandaris and Murex trunculus, which are the older names for Bolinus brandaris and Hexaplex ...
6,6'-Dibromoindigo is an organic compound with the formula (BrC 6 H 3 C (O)CNH) 2. A deep purple solid, the compound is also known as Tyrian purple, a dye of historic significance. Presently, it is only a curiosity, although the related derivative indigo is of industrial significance. The molecule consists of a pair of monobrominated indole ...

A pigment in Tyrian purple, 6-dibromoindirubin, may slow the spread of a variety of cancers including lung, stomach, colon, abdominal, and leukaemia cancers. [9] Extracts from the glands of Hexaplex trunculus showed possible adhesion inhibition of cervical and glioblastoma cells, which can decrease the frequency of tumor formation. [10]
