Attempts to develop a more acid labile protecting group than the Pmc group has led to the preparation of the related Pbf group, which was shown to be 1.2-1.4 times more sensitive to TFA then the Pmc group. ... [Pg.867]

The sulfation of serine and threonine in solution after solid-phase peptide chain assembly can be accomplished with DMF-SO3 in DMF-pyridine (4 1 v/v) at 4°C [213] (see also Section III.B) or by exploiting a side reaction observed during the removal of the 2,2,5,7,8-pentamethyl-chroman-6-sul-fonyl (Pmc) group from arginine with TEA under nonaqueous conditions [199,214,215]. The arylsulfonyl transfer reaction [214] has obvious practical limitations because of the sequence requirement and potential side reactions related to the lack of scavengers in the cleavage-deprotection mixture. [Pg.463]

Sodium pyrophosphate peroxohydrate, Na4P202 2H2O2, was made commercially by PMC in the 1960s but was discontinued. It is less stable than sodium peroxoborate and sodium carbonate peroxohydrate in the soHd state, but more stable than these in solution. Many other phosphate peroxohydrates of the Group 1 and Group 2 metals are known but have found no uses. [Pg.97]

Pseudomembranous colitis (PMC) results from toxins produced by Clostridium difficile. It occurs most often in epidemic fashion and affects high-risk groups such as the elderly, debilitated patients, cancer patients, surgical patients, any patient receiving antibiotics, patients with nasogastric tubes, or those who frequently use laxatives. [Pg.443]
