Influence of cytotoxic drugs on platelet functions in vitro. III. Peptichemio. 1975

P Klener, and P Kubisz, and J Suranová

The influence of Peptichemio (m-dichloroethyl-amino-l-phenyl-alanyl-peptide complex) on the following platelet functions was studied: aggregation, release of platelet factor 4, availability of platelet factor 3, acid phosphatases and reptilase clot retraction. Concentrations of the drug corresponding to that found in plasma of treated patients did not significantly influence platelet functions. Concentrations 10 times higher brought about an inhibition. It is concluded that after current dosage of Peptichemio, bleeding disorders caused by impairement of platelet functions are improbable.

UI	MeSH Term	Description	Entries
D009588	Nitrogen Mustard Compounds	A group of alkylating agents derived from mustard gas, with the sulfur replaced by nitrogen. They were formerly used as toxicants and vesicants, but now function as antineoplastic agents. These compounds are also powerful mutagens, teratogens, immunosuppressants, and carcinogens.	Compounds, Nitrogen Mustard,Mustard Compounds, Nitrogen
D010440	Peptichemio	A mixture of six synthetic oligopeptides, each containing MELPHALAN. It is used as a broad-spectrum antineoplastic due to its alkylating and antimetabolic actions but, is toxic to bone marrow, gastrointestinal system and vasculature.
D010974	Platelet Aggregation	The attachment of PLATELETS to one another. This clumping together can be induced by a number of agents (e.g., THROMBIN; COLLAGEN) and is part of the mechanism leading to the formation of a THROMBUS.	Aggregation, Platelet
D010977	Platelet Factor 3	A phospholipid from the platelet membrane that contributes to the blood clotting cascade by forming a phospholipid-protein complex (THROMBOPLASTIN) which serves as a cofactor with FACTOR VIIA to activate FACTOR X in the extrinsic pathway of BLOOD COAGULATION.	PF 3,Factor 3, Platelet
D012103	Batroxobin	A proteolytic enzyme obtained from the venom of fer-de-lance (BOTHROPS ATROX). It is used as a plasma clotting agent for fibrinogen and for the detection of fibrinogen degradation products. The presence of heparin does not interfere with the clotting test. Hemocoagulase is a mixture containing batroxobin and factor X activator. EC 3.4.21.-.	Defibrol,Hemocoagulase,Defibrase,Reptilase,Reptilase-DEF,Reptilase DEF
D001792	Blood Platelets	Non-nucleated disk-shaped cells formed in the megakaryocyte and found in the blood of all mammals. They are mainly involved in blood coagulation.	Platelets,Thrombocytes,Blood Platelet,Platelet,Platelet, Blood,Platelets, Blood,Thrombocyte
D002118	Calcium	A basic element found in nearly all tissues. It is a member of the alkaline earth family of metals with the atomic symbol Ca, atomic number 20, and atomic weight 40. Calcium is the most abundant mineral in the body and combines with phosphorus to form calcium phosphate in the bones and teeth. It is essential for the normal functioning of nerves and muscles and plays a role in blood coagulation (as factor IV) and in many enzymatic processes.

D003094	Collagen	A polypeptide substance comprising about one third of the total protein in mammalian organisms. It is the main constituent of SKIN; CONNECTIVE TISSUE; and the organic substance of bones (BONE AND BONES) and teeth (TOOTH).

D003864	Depression, Chemical	The decrease in a measurable parameter of a PHYSIOLOGICAL PROCESS, including cellular, microbial, and plant; immunological, cardiovascular, respiratory, reproductive, urinary, digestive, neural, musculoskeletal, ocular, and skin physiological processes; or METABOLIC PROCESS, including enzymatic and other pharmacological processes, by a drug or other chemical.

D004837	Epinephrine	The active sympathomimetic hormone from the ADRENAL MEDULLA. It stimulates both the alpha- and beta- adrenergic systems, causes systemic VASOCONSTRICTION and gastrointestinal relaxation, stimulates the HEART, and dilates BRONCHI and cerebral vessels. It is used in ASTHMA and CARDIAC FAILURE and to delay absorption of local ANESTHETICS.
