MedChemComm September 2012 Front Cover Image For The “Examining The Effects Of Vitamin B12 Conjugation…” Paper

Blogging a blog post recently blogged here in a post, with a zoom-in below because no decent-sized version of the same can be found on the MedChemComm site, all pertaining to the “Examining the effects of vitamin B12 conjugation on the biological activity of insulin: a molecular dynamic and in vivo oral uptake investigation” article from Susan Clardy-James, myself, Timothy J. Fairchild and Robert P. Doyle in ChemMedComm (available at pubs.rsc.org/en/Content/ArticleLanding/2012/MD/C2MD20040F).

The MedChemComm post also provides the caption for the cover (below), which I reproduce below for context:

Oral delivery of drugs aims to open up new areas of peptide/protein therapeutics associated with the removal for a need for injections. The major problems facing oral delivery of peptides/proteins is hydrolysis/proteolysis in the gastrointestinal tract and an inefficient uptake mechanism for peptides/proteins from the tract. Robert P. Doyle et al. are interested in the use of the vitamin B12 dietary uptake pathway to address these hurdles. In this paper Doyle et al. report the synthesis, purification and characterisation of a new B12-insulin conjugate attached between the B12 ribose hydroxyl group and insulin PheB1.
