The Prostaglandins: Basic Chemistry and ..

In the second paper, the Nicolaou lab identified a macrolactone derivative, formed by joining two functional groups together, as a promising chemotherapy agent to fight a variety of cancers. That publication in the described the synthesis of dozens of prostaglandin derivatives. Nicolaou said the National Institutes of Health’s National Cancer Institute (NCI) tested their cytotoxicity against a variety of cancer cell samples.

Stereocontrolled organocatalytic synthesis of prostaglandin PGF2α in seven steps

Chamomile as anti-inflammatory: The anti-inflammatory effect of chamomile is partly due to its inhibitory action on the activityof COX-2 enzyme and thus on the release oflipopolysaccharide-induced prostaglandin E2 – a mechanism of action that parallels that of non-steroidal anti-inflammatory drugs (NSAIDs).[16] The inhibitoryaction of chamomile against tumor growth, on the other hand, comes from apigenin, one of chamomile’s major bioactive constituents.

The prostaglandin the Nicolaou lab synthesized had been isolated in 2011 as a  formed from  that is found primarily in fish oil.

Luteolin: According to a recent South Korean study, luteolin has the potential to be a potent anti-angiogenic agent for retinalneovascularization because of its abilityto block reactive oxygen species (ROS) production and suppress the expression of vascular endothelial growth factor (VEGF). [25] Luteolin and quercetin are alsoeffective agents against leishmaniasis, both of which deter the growth of promastigotes and amastigotes in vitroand inhibit DNA synthesisin promastigotes. [26]

R. B. Woodward weighed in four years later with a slightly shorter formal synthesis that relied on very similar tactics, but would probably be much harder to make asymmetric. As I had it drawn out for a Woodward Wednesday that never seemed to happen, it's shown below for comparison. Although the chemistry is quite simple and easy to follow it does have a few less common steps including a Payne epoxidation and a Tiffeneau-Demjanov Rearrangement. I don't think I've ever met anyone who’s done either.

Sanity checks!
The title of the paper is “Stereocontrolled organocatalytic synthesis of prostaglandin PGF2a in seven steps” but gave “the product in just six steps”?
In the last step the phosphonium is one carbon short, and how can a 47% yield give 1.9 g of a lower-MW (lost the heavy TBS) product starting from only 1.4 g?
A couple of the sentences in the optimization paragraph are backwards. Normally you’s expect the 2nd aldol to be in favor of the intramolecular reaction and the second catalyst could not be present at the same time.

The biological meaning of prostaglandin-levels - …

NSAIDS reduce pain and inflammation within the body by reducing the production of prostaglandins (pro-inflammatory chemicals). Prostaglandins are pro-inflammatory chemicals which are normally produced by the body as a consequence of tissue damage and have a significant role in the processes of inflammation, pain and fever. Many of the effects of NSAID’s can therefore be attributed to the inhibition of prostaglandin synthesis. Prostaglandins are released by the damaged tissue, i.e. at the source of the pain, therefore NSAID’s are described as peripherally acting analgesics . However, prostaglandins also have a protective function (gastric, renal support & platelet activation).

The biological meaning of prostaglandin ..

Until recently it was unclear the exact mechanism by which paracetamol works, however, recent evidence suggests that paracetamol also works by reducing the synthesis of specific prostaglandins .


Corey achieved the first synthesis of prostaglandin F2a in 1969 in 17 steps; which wasn't a bad benchmark for the year and the target! He then spent a lot of time improving on his first generation route, and it’s interesting to read his follow up papers for this purpose.[2] In fact, despite a few flaws, Corey’s work actually became the basis of the 20-step commercial route used by Pfizer for commercial production of Latanoprost. I had Corey's original route drawn up for something else, so I've included it below.
