Prostaglandin D2 (PGD2) is one of the five principal prostaglandins enzymatically derived from PGH2. It is abundantly generated in the cerebrospinal fluid (CSF) by lipocalin-type PGD synthase and in peripheral regions by myeloid cells, such as mast cells and basophils, via leukocyte-type PGD synthase. The compound 1,25-trans-PGD2 is an isomer of PGD2, characterized by the alteration of the double bond between carbons 5 and 6 from cis(Z) to trans(E). This trans isomer, found as a 2-5% impurity in most commercial PGD2 bulk drug preparations, is primarily synthesized as an analytical standard to identify and quantify this impurity. Based on existing studies of trans isomers of F-type prostaglandins, 5-trans-PGD2 likely exhibits biological activity comparable to its cis isomer, although no specific published reports confirm this for 5-trans-PGD2.

This compound is applied in breast cancer cell research [1] [2].

Latanoprost is an F-series prostaglandin analog which has been approved for use as an ocular hypotensive drug. 5-trans Latanoprost is an isomer of latanoprost wherein the double bond between carbons 5 and 6 has been changed from cis (Z) to trans (E). The trans isomer of latanoprost occurs as an impurity of between 2-5% in most commercial preparations of the bulk drug product. The present compound was prepared primarily as an analytical standard for detection and quantitation of this impurity. From what can be inferred from the study of other trans isomers of F-type prostaglandins, 5-trans latanoprost's biological activity is likely to be similar to that of the cis isomer. However, there are no specific published reports on the biological activity, and on the intraocular hypotensive activity in particular, of 5-trans latanoprost.

Latanoprost is an F-series prostaglandin (PG) analog which has been approved for use as an ocular hypotensive drug.

The trans isomer of latanoprost occurs as an impurity in commercial preparations of the bulk drug product. The present compound was prepared primarily as an analytical standard for detection and quantitation of this impurity. From what can be inferred from the study of other trans isomers of F-type prostaglandins, the biological activity of this isomer is likely to be similar to that of the cis isomer.
