Reconstitution of neocarzinostatin (NCS).

Neocarzinostatin (NCS) and microtubule-associated kinase.

Clinical trials of a new antitumor polypeptide: neocarzinostatin (NCS).

Neocarzinostatin, a new polypeptide which had shown antitumor activity in animals, was given to 17 patients with advanced malignant tumors. Five of 17 patients showed objective regression of tumors and disappearance of clinical symptoms. On account of the limited clinical experiences, no assertion can be made as to the range of therapeutic indication or to the comparison of neocarzino statin wi...

Peroxy acid as a partial structure of neocarzinostatin (NCS) chromophore.

Sir: Neocarzinostatin (NCS) chromophore was obtained as a separable component from polypeptide antitumor antibiotic NCS by us1,2) and GOLDBERG et al.3,4), independently. This chromophore, which was demonstrated to have biological activities such as growth inhibition of bacterial and tumor cells1), inhibition of DNA synthesis in cultured mammalian cells, strand scission of DNA in vitro and in vi...

Absence of anti-neocarzinostatin (NCS) antibody production in leukemia patients treated with NCS.

Neocarzinostain (NCS) was first used by Hiraki and his colleagues for induction chemotherapy in acute leukemia. This new anti-tumor agent is a polypeptide with a high molecular weight of 10,700 daltons. Anti-NCS antibody was produced in rabbits administered NCS intramuscularly with or without adjuvant. The production of anti-NCS antibody in patients treated with NCS was investigated. Forty thre...

Absorption, distribution and excretion of neocarzinostatin (NCS) in mice after oral administration.

Distribution, excretion and toxicity of an antitumor protein, neocarzinostatin (NCS) were examined in mice after oral administration. The oral LD50 1 g/kg after intravenous injection. After oral administration of 200 mg/kg of NCS, the tissue level was low but detectable in lung, skin and pancreas in addition to the tissues of the gastrointestinal tract. The NCS level in lung and skin remained c...
