(±)?-?arabinose

Arabinose (DL-Arabinose), also known as (+ -)-arabinose or aloe sugar. Arabinose has been primarily detected in feces. Within the cell, Arabinose is primarily located in the cytoplasm. Arabinose exists in all eukaryotes, ranging from yeast to humans. Outside of the human body, Arabinose can be found in sweet basil and tamarind.

L-(+)-Arabinose selectively inhibits intestinal sucrase in a non-competitive manner, thereby preventing glucose elevation induced by sucrose intake.

Inexpensive starting material for chiral synthesis.

D-(-)-Arabinose is a reducing sugar useful as a substrate in analysis of arabinose isomerases and synthesis of D-erythroascorbic acid in yeast. It shows strong growth inhibition against the Caenorhabditis elegans with an IC50 of 7.5 mM.

Thyminose induces apoptosis by inhibiting glutathione synthesis and increasing its efflux.

Ancitabine hydrochloride (NSC 145668 HCl) is the hydrochloride salt of a cytarabine congener prodrug with antineoplastic activity. Upon administration, ancitabine is slowly hydrolyzed into cytarabine. Subsequently, cytarabine is converted to the triphosphate form within the cell and then competes with cytidine for incorporation into DNA. Because the arabinose sugar sterically hinders the rotation of the molecule within DNA, DNA replication ceases, specifically during the S phase of the cell cycle. Cytarabine agent also inhibits DNA polymerase, resulting in a decrease in DNA replication and repair. Compared to cytarabine, a more prolonged, consistent cytarabine-mediated therapeutic effect may be achieved with ancitabine because of the slow hydrolytic conversion of ancitabine to cytarabine.

D-(+)-Fucose is a non-metabolizable analog of l-arabinose and an inducer of β-methylgalactoside permease. It inhibits the induction of the l-arabinose manipulator and blocks the growth of Escherichia coli B r on mineral salts medium with l-arabinose.

D-Ribose(mixture of isomers) (D-(-)-Ribose), commonly referred to as simply ribose, is a five-carbon sugar found in all living cells. Ribose is not an essential nutrient because it can be synthesized by almost every tissue in the body from other substances, such as glucose. It is vital for life as a component of DNA, RNA, ATP, ADP, and AMP.
