The bioavailability in man of ICRF-159 a new oral antineoplastic agent

The Journal of Pharmacy and Pharmacology
P J CreavenD A Alford


The bioavailability of the antineoplastic agent, ICRF-159, has been examined in 12 patients receiving the drug in single and subdivided dose schedules in an attempt to account for the differences in toxicity found with the different schedules clinically. Recovery of radioactivity in the urine after single large doses (13.3-19.4 g) was 8.5 +/- 3.0% of the administered dose. After doses of 3.8-5.55 g recovery was 22.7 +/- 10.5% and after the same dose subdivided into 3 equal aliquots it was 52 +/- 8.7%. Unrecovered radioactivity was largely accounted for in the faeces. Plasma radioactivity levels in 2 patients after high and low dose were equivalent. Toxicity of the drug paralleled urinary recovery of radioactivity. It is concluded that schedule dependence of toxicity of ICRF-159 is at least partly due to bioavailability factors.

Coronaviruses encompass a large family of viruses that cause the common cold as well as more serious diseases, such as the ongoing outbreak of coronavirus disease 2019 (COVID-19; formally known as 2019-nCoV). Coronaviruses can spread from animals to humans; symptoms include fever, cough, shortness of breath, and breathing difficulties; in more severe cases, infection can lead to death. This feed covers recent research on COVID-19.

Chronic Fatigue Syndrome

Chronic fatigue syndrome is a disease characterized by unexplained disabling fatigue; the pathology of which is incompletely understood. Discover the latest research on chronic fatigue syndrome here.

Systemic Juvenile Idiopathic Arthritis

Systemic juvenile idiopathic arthritis is a rare rheumatic disease that affects children. Symptoms include joint pain, but also fevers and skin rashes. Here is the latest on this disease.

Chromatin Regulation and Circadian Clocks

The circadian clock plays an important role in regulating transcriptional dynamics through changes in chromatin folding and remodelling. Discover the latest research on Chromatin Regulation and Circadian Clocks here.

Central Pontine Myelinolysis

Central Pontine Myelinolysis is a neurologic disorder caused most frequently by rapid correction of hyponatremia and is characterized by demyelination that affects the central portion of the base of the pons. Here is the latest research on this disease.

Myocardial Stunning

Myocardial stunning is a mechanical dysfunction that persists after reperfusion of previously ischemic tissue in the absence of irreversible damage including myocardial necrosis. Here is the latest research.

Pontocerebellar Hypoplasia

Pontocerebellar hypoplasias are a group of neurodegenerative autosomal recessive disorders with prenatal onset, atrophy or hypoplasia of the cerebellum, hypoplasia of the ventral pons, microcephaly, variable neocortical atrophy and severe mental and motor impairments. Here is the latest research on pontocerebellar hypoplasia.

Cell Atlas Along the Gut-Brain Axis

Profiling cells along the gut-brain axis at the single cell level will provide unique information for each cell type, a three-dimensional map of how cell types work together to form tissues, and insights into how changes in the map underlie health and disease of the GI system and its crosstalk with the brain. Disocver the latest research on single cell analysis of the gut-brain axis here.
