P264, P270, P301+P316, P321, P330, P405, and P501 (click each P-code to see the statement)

Aggregated GHS information provided per 52 reports by companies from 5 notifications to the ECHA C&L Inventory.

Possesses cytostatic, immunosuppressive, and antineoplastic properties; [ChemIDplus] Evidence of neurotoxicity in experimental animals; [HSDB] Causes urine changes in 3-day intermittent intraperitoneal studies of rats; Causes muscle weakness and hemorrhage in 15-day intermittent intravenous studies of dogs; Oral administration in humans causes anorexia and nausea or vomiting; [RTECS] An irritant; Harmful by ingestion; [Alfa Aesar MSDS]

WHEN ADDED TO CHICK EMBRYO FIBROBLAST CULTURES WHICH HAD BEEN INFECTED WITH AVIAN SARCOMA VIRUS, CYCLOLEUCINE DID NOT SIGNIFICANTLY AFFECT VIRUS YIELDS BUT INHIBITED METHYLATION OF VIRAL RNA AT 5'-TERMINAL STRUCTURES.

IN BHK CELLS INFECTED WITH VESICULAR STOMATITIS VIRUS (VSV), CYCLOLEUCINE INHIBITED VIRUS SYNTHESIS BY 99% & REDUCED SIGNIFICANTLY THE SIZE OF VSV MESSENGER RNA SPECIES.

TREATMENT OF DEVELOPING RATS RESULTED IN CHANGES OF BRAIN & SPINAL CORD PHOSPHOLIPID CONTENT & FATTY ACIDS. DECR IN ETHANOLAMINE PHOSPHOLIPID CONTENT & INCR IN SATURATED FATTY ACIDS OF ETHANOLAMINE PHOSPHOLIPID. MINOR FATTY ACIDS CHANGES IN PHOSPHATIDYL CHOLINE.

CONSIDERABLE MYELIN SPLITTING WAS SHOWN BY ELECTRON MICROSCOPIC EXAMINATION OF THE SPINAL CORDS OF CYCLOLEUCINE-AFFECTED RATS.

LEVELS OF (14)C IN LIVER & PANCREAS WERE RESPECTIVELY EIGHTFOLD & TWOFOLD THOSE IN BLOOD, 15 MIN AFTER IV DOSE OF [(14)C]-1-AMINOCYCLOPENTANECARBOXYLIC ACID TO RHESUS MONKEYS. (14)C LEVELS IN THESE TISSUES WERE SIMILAR TO THOSE IN BLOOD AFTER 24 HR.

WHEN ADMIN TO MICE CYCLOLEUCINE ACCUM IN TISSUES AT LEVELS BETWEEN 0.02 & 1.29 MG/ML. MOST OF REMAINING 2% WAS ASSOC WITH PROTEIN. ACCUM AGAINST CONCN GRADIENT OCCURRED IN KIDNEY, IN SPLEEN TO GREATER EXTENT & TO MUCH GREATER DEGREE IN PANCREAS. THE DISTRIBUTION RATIOS FOR CNS TISSUE, KIDNEY & SPLEEN DID NOT CHANGE AS FUNCTION OF PLASMA CYCLOLEUCINE CONCN OR OF TIME BETWEEN 4 & 40 DAYS AFTER ADMIN TO MICE. 5 DAYS AFTER ADMIN OF CYCLOLEUCINE TO MICE, HEPATIC CYCLOLEUCINE DISTRIBUTION RATIO WAS CONSIDERABLY GREATER THAN UNITY AT THE LOWEST DOSES & INCR VARIABLY WITH INCR CYCLOLEUCINE PLASMA LEVELS.

A synthetic amino acid used in amino acid transport studies and in testing for immunosuppression in mice; [Merck Index] Used as experimental tumor screening agent; [HSDB]

BIOLOGICAL TESTING MATERIALS FOR IMMUNOSUPPRESSIVE PROPERTIES IN MICE; FOR AMINO ACID TRANSPORT STUDIES
