Wrapping up 2013

There were a lot of papers that I read last year and really liked.  I would like to write a full critique, but I just don't have time.  So here is my twitter critique (<150 words - I know that twitter uses characters, but give me a break.)

The quiet renaissance of protein nuclear magnetic resonance


Paul Barrett and a cast of thousands

Super well-written review.  A call to arms to NMR spectroscopists to embrace NMR as a broad problem-solving tool rather than machine that generates PDB files.

Mycalol: A natural lipid with promising cytotoxic properties against human anaplastic thyroid carcinoma cells


Adele Cutignano and co-workers;jsessionid=E7C1B2F402EF5A4BA96E06EFFEF70D1F.f04t03

A great natural products structure elucidation paper.  This paper is what really inspired me to start this blog.  The authors isolated a lipid from a sponge they found in Antarctica.  The molecule has five stereocenters and it would have been a pain in the ass to assess stereochemistry using NOE and J coupling.  The authors use CD and Mosher's method and a lot of clever logic.  A+

Characterization of Cyclopentyllithium and Cyclopentyllithium Tetrahydrofuran Complex


Su, Hopson and Williard

The first of three JACs papers published by these authors this fall.  Good grief.  I won't get three JACS papers in a lifetime.  These guys got three during the football season!  This one is probably my favorite for the cool use of DOSY to explore the equilibrium between a hexameric and tetrametric molecule.   

The influence of electronic modifications on rotational barriers of bis-NHC-complexes as observed by dynamic NMR spectroscopy


Kolmer, Kaltschnee, Schmidts, Peeck, Plenio and Thiele (so many Germans and no umlauts!)

A great physical organic chemistry paper regarding Grubbs catalysts.  Quantitative dynamics to measure rotational barriers and a clear relationship between redox properties and rotational barrier.  Nice work.

Direct Measurements of the Mn(II) hydration state in metal complexes and metalloproteins through 17O NMR linewidths


Gale, Zhu and Caravan

NMR tricks to assess the hydration state of metal complexes.  Relaxivity measurements.  Sign me up.

  1. Thanks Mr. Sit and Spin :) These are great finds and I enjoy your humorous commentary!
