Synthesis of novel papulacandin d analogs and evaluation of their antifungal potential

Systemic fungal infections are a growing problem in contemporary medicine and few drugs are licensed for therapy of invasive fungal infections. Differences between fungi and humans, like the presence of a cell wall in fungal cells, can be explored for designing new drugs. (1,3)-beta-D-glucan synthase, an enzyme that catalyzes the synthesis of (1,3)-beta-D-glucan, a structural and essential component of the fungal cell wall, is absent in mammals and this makes it an excellent target for the development of new antifungal agents. Papulacandins are a family of natural antifungal agents targeting (1,3)-beta-D-glucan synthase. In this study we describe the synthesis and biological evaluation of two new Papulacandin analogs as potential (1,3)-beta-D-glucan synthase inhibitors.

I hope this article can help some friends in scientific research. I am very proud of our efforts over the past few months and hope to 10343-06-3, help many people in the next few years., Reference of 10343-06-3

An acceptor analogue of beta-1,4-galactosyltransferase: Substrate, inhibitor, or both?

Many glycosyltransferase inhibitors in the literature are structurally derived from the donor or acceptor substrate of the respective enzyme. A representative example is 2-naphthyl beta-D-GlcNAc, a synthetic GlcNAc glycoside that has been reported as a galactosyltransferase inhibitor. This GlcNAc derivative is attractive as a chemical tool compound for biological and biochemical studies because of its reported potency as an inhibitor, and its short and straightforward synthesis from readily available starting materials. We report that in our hands, 2-naphthyl beta-D-GlcNAc behaved, unexpectedly, as an acceptor substrate of the inverting beta-1,4-galactosyltransferase (beta-1,4-GalT) from bovine milk. This substrate activity has not previously been described. We found that 2-naphthyl beta-D-GlcNAc can be an acceptor substrate both for recombinantly expressed beta-1,4-GalT, and for a commercial batch of the same enzyme, and both in the presence and absence of bovine serum albumin (BSA). As expected for a full acceptor substrate, this substrate activity was time- and concentration-dependent. Additional experiments show that the observed inhibitor/substrate switch is facilitated by a phosphatase that is an essential component of our enzyme-coupled glycosyltransferase assay. These findings suggest that the behaviour of 2-naphthyl beta-D-GlcNAc and related acceptor-based glycosyltransferase inhibitors is strongly dependent on the individual assay conditions. Our results therefore have important implications for the use of 2-naphthyl beta-D-GlcNAc and related glycosides as tool compounds in glycobiology and glycobiochemistry.

13C NMR Studies on Trifluoroacetyl Derivatives of 2-Acetamido-2-deoxyhexoses

The effect of trifluoroacetylation on the 13C chemical shifts of 2-acetamido-2-deoxyhexoses was examined.Studies of the 2-acetamido derivatives of glucose, galactose and mannose established that no regular trend in the 13C shifts occured on trifluoroacetylation.This was in marked contrast to the results obtained for the 1H chemical shifts.

CC chemokine receptor-3 (CCR3) antagonists: Improving the selectivity of DPC168 by reducing central ring lipophilicity

DPC168, a benzylpiperidine-substituted aryl urea CCR3 antagonist evaluated in clinical trials, was a relatively potent inhibitor of the 2D6 isoform of cytochrome P-450 (CYP2D6). Replacement of the cyclohexyl central ring with saturated heterocycles provided potent CCR3 antagonists with improved selectivity against CYP2D6. The favorable preclinical profile of DPC168 was maintained in an acetylpiperidine derivative, BMS-570520.

The Amadori rearrangement as glycoconjugation method: Synthesis of non-natural C-glycosyl type glycoconjugates

The Amadori rearrangement was investigated as a potential method for the conjugation of carbohydrate moieties to suitable amino components. Starting from selected aldoheptoses, which are readily available by means of the Kiliani-Fischer C-elongation reaction of the corresponding aldohexoses, glycoconjugates presenting D-gluco, D-manno and D-galacto as well as GlcNAc motifs have been synthesised. Following this strategy, non-natural C-glycosyl type glycoconjugates, which can be utilised as building blocks for the composition of larger molecular constructions, are available by a very short synthetic approach.
