Glycosylation is a major modification of secreted and cell surface proteins, and the resultant glycans show considerable heterogeneity in their structures. To understand the biological processes arising from each glycoform, the preparation of homogeneous

Toll-like receptor 2 (TLR2) is a bridge between innate immunity and adaptive immunity. TLR2 agonists have been exploited as potential vaccine adjuvants and antitumor agents. However, no TLR2 agonists have been approved by FDA up to now. To discover drug-like TLR2 selective agonists, a novel series of Pam3CSK4 derivatives were designed based on the crystal structure of hTLR2-hTLR1-Pam3CSK4 complex, synthesized and evaluated for their immune-stimulatory activities. Among them, 35c was identified as a murine-specific TLR2 agonist, while 35f was a human-specific TLR2 agonist. Besides, 35d (human and murine TLR2 agonist) showed TLR2 agonistic activity comparable to Pam3CSK4, which included: elevated IL-6 expression level (EC50 = 83.08 ± 5.94 nM), up-regulated TNF-α and IL-6 mRNA expression and promoted maturation of DCs through activating the NF-κB signaling pathway. TLRs antibodies test showed that 35a and 35d were TLR2/1 agonists, while 35f was a TLR2/6 agonist.
Stereoselective synthesis of orthogonally protected α- methylnorlanthionine

As the unusual amino acid norlanthionine (nor-Lan) has previously been incorporated into cyclic peptide analogues of the ring C of lantibiotic nisin, we report here the stereoselective synthesis of the new (S,R)- and (R,R)-α-methylnorlanthionines (α-Me-no
Tetra-n-butylammonium Oxone. Oxidations under Anhydrous Conditions
Trost, Barry M.,Braslau, Rebecca

Tetra-n-butylammonium Oxone, readily prepared as a white solid from commercially available Oxone, performs oxidations in anhydrous methylene chloride.Under these conditions, sulfides are oxidized to sulfones in the presence of amines, ketones, esters, car
