A ribonucleoside antibiotic synergist and adenosine deaminase inhibitor isolated from Nocardia interforma and Streptomyces kaniharaensis. It is proposed as an antineoplastic synergist and immunosuppressant.

Drugs that inhibit ADENOSINE DEAMINASE activity.

An enzyme that catalyzes the deamination of AMP to IMP. EC 3.5.4.6.

Nucleosides in which the purine or pyrimidine base is combined with ribose. (Dorland, 28th ed)

Catalyze the hydrolysis of nucleotides with the elimination of ammonia.

Catalyze the hydrolysis of nucleosides with the elimination of ammonia.

An enzyme that catalyzes the hydrolysis of ADENOSINE to INOSINE with the elimination of AMMONIA.

Adenine nucleotide containing one phosphate group esterified to the sugar moiety in the 2'-, 3'-, or 5'-position.

A nucleoside that is composed of ADENINE and D-RIBOSE. Adenosine or adenosine derivatives play many important biological roles in addition to being components of DNA and RNA. Adenosine itself is a neurotransmitter.
