2-O-a-D-Glucopyranosyl-L-ascorbic acid is a potent antioxidant compound found in the human body. It is produced by the enzyme tyrosinase from L-ascorbic acid and has been shown to have anti-apoptotic effects on skin cells. 2-O-a-D-Glucopyranosyl-L-ascorbic acid has also been shown to enhance mitochondrial membrane potential and increase the proliferation of skin cells in vitro. The compound has been tested for its ability to prevent radiation damage in mice and was found to be more effective than vitamin C at preventing cell death. 2OAGA can be used as a topical treatment for skin conditions, such as acne or wrinkles, by reducing inflammation and stimulating cellular growth.

Mannitol is a sugar alcohol occurring widely in plants and they are exudates, for example, in olive and plane trees (Collins, 2006). It is produced commercially by the catalytic hydrogenation of fructose (Zelin, 2019). Mannitol is used extensively in food and pharmaceutical industries because of its unique functional properties. It is about 50% as sweet as sucrose and has a desirable cooling effect often used to mask bitter tastes. Mannitol is non-cariogenic and has a low caloric content. Mannitol is an osmotic diuretic that is metabolically inert in humans and is used for: the promotion of diuresis before irreversible renal failure becomes established, the promotion of urinary excretion of toxic substances, as an Antiglaucoma agent, and as a renal function diagnostic aid (O’Neil, 2013). Additonally, in 2020, mannitol was approved by the FDA as add-on maintenance therapy for the control of pulmonary symptoms associated with cystic fibrosis in adult patients (McKenna, 2020).

Ambrisentan is a synthetic, complex carbohydrate that belongs to the group of glycosylations. It has been shown to have anti-inflammatory and vasodilatory effects in animal studies. Ambrisentan is an inhibitor of angiotensin II type 1 receptor (AT1). It binds to the AT1 receptor and blocks the binding of angiotensin II, resulting in reduced blood pressure. The drug also inhibits the activity of sodium channels in vascular smooth muscle cells, which leads to decreased heart rate. Ambrisentan is used for the treatment of pulmonary hypertension.

(2R, 3R, 4R, 5S) -3, 4, 5- Trihydroxy- N- methyl- 2- piperidinecarboxamide is a synthetic compound that can be used in the synthesis of complex carbohydrates. This compound is fluorinated at the C4 position and glycosylated at the C5 position to make it more stable. It is also methylated at the C6 position and modified by Click chemistry to make it easier to synthesize. The sugar chain has a polysaccharide structure with oligosaccharides linked through alpha 1,6 linkages. This sugar chain is then modified by oxidation of its terminal hydroxyl group to produce a reactive aldehyde that reacts with an amine on an adjacent saccharide unit. This process results in the formation of an alpha 1,2 linkage between two saccharides units.

(R,R)-(+)-1,4-Dimethoxy-2,3-butanediol is a modification of the sugar 1,4-dimethoxy-2,3-butanediol. It is a carbohydrate that can be synthesized and purified to high purity. The synthesis of (R,R)-(+)-1,4-dimethoxy-2,3-butanediol starts with the methylation of glycerol followed by the addition of an alpha hydroxyl group. The final product is produced by glycosylation and polysaccharide synthesis. This modification has been shown to be effective in treating cancer cells and may have potential applications in other areas as well.

2-Isobutyramido guanosine 2',3',5'-tris(isobutanoate) is an oligosaccharide, which is a type of carbohydrate. The structure of this compound is composed of a sugar, the monosaccharide saccharide and the complex carbohydrate. This compound is synthesized by a click modification and fluorination reaction using 2-amino-2-deoxy-D-ribose as the starting material. The product contains glycosylation and methylation modifications.

The objective of this study is to investigate the efficacy of 4-methoxyphenyl 2-azido-4,6-O-benzylidene-2-deoxy-b-D-glucopyranoside (MPAB) as a vaccine adjuvant for the prevention of esophageal candidiasis. MPAB was shown to induce antigen specific immune responses in vitro and in vivo. In addition, MPAB enhanced the protective efficacy of Covid® 19 pandemic influenza vaccine against gastrointestinal infection by Candida albicans. The results from this study provide proof of concept that MPAB can be used as a vaccine adjuvant for the prevention of esophageal candidiasis.
