The Western Canadian Medicinal Chemistry Workshop is back! Come for a weekend in beautiful Saskatoon and share your work in pharmaceutical, bioorganic, biophysical and related areas of chemistry! #ChemSky

A poster advertising the 8th WCMCW, which I made myself! It’s September 25–27, and features young speakers from across western Canada.

You put the comforter on the floor to make the bed and…

Your shipment that clearly indicates that it contains glass will be fine because it’s also marked *fragile*!

This is as fifties a movie as ever fiftiesed

A woman (Dorothy Malone) is n a plaid shirt holds a drink and smirks wickedly at a man (Rock Hudson) in a white shirt and a thin dark red tie, who looks at her in a mixture of confusion and disgust. Behind them is a candelabra and a window with sheer shades and a gold curtain.

Unexpected chemistry content in tonight’s movie, A Kiss Before Dying (1956)! A YOUNG Robert Wagner slips into the lab to help himself to some arsenic (in an unfathomable plan to help Joanne Woodward out of his life).

Robert Wagner in a blue suit like any normal college student, looks over his shoulder at another student pouring a liquid, shelf of chemicals and flasks behind them. She wears an apron as PPE, as was the style at the time.

Robert Wagner holding an envelope I front of him. There are olde tyme rubber gloves on the bench in front of him, and several bottles in front of him, one clearly labeled “arsenic”.

Canada Day is always a good day to look for cactus blooms here in Saskatchewan!

Through a land so wild and savage!

Glen’s Jackrabbit photo with Gen’s pet rabbit Franklin added so it looks like they are bounding together through the night. The post is a line from Stan Rogers’ Northwest Passage, about the Franklin expedition.

Another DIY project comes to its natural conclusion 😑

We also knew that the resulting products (called benzylidenepyruvates) could be converted to substituted cinnamic acids in a rapid reaction with hydrogen peroxide. When we looked at rates of reactions, the fastest substrate for the enzyme was para-methoxybenzaldehyde. 8/

Two step chemoenzymatic process converting para-methoxybenzaldehyde and pyruvate to para-methoxycinnamic acid.

A little science: I knew octinoxate was a UV absorber because I recognized the long conjugated pi-system, which can allow molecules to absorb light in the ultraviolet region of the electromagnetic spectrum. I started using it in class as an exercise in drawing resonance structures. 6/

Two resonance structures of an ester of para-methoxycinnamate. Blue arrows show the apparent movement of pairs of electrons. It shows that the electrons in this system are delocalized.

Like many chemists, I read the backs of bottles to learn what's in them. Many (~20?) years ago, I looked at a bottle of moisturizer that said it was SPF 15. I saw "octyl methoxycinnamate" and knew this was the sunscreen ingredient. It also goes by the name octinoxate. Here's the structure: /5

The structure of octinoxate, or 2-ethylhexyl para-methoxycinnamate.

It was brief but intense… back with the guys who wisely remained on the sofa
