Symmetric covalent linkage of N-(6-aminohexyl)-5-chloro-1-naphthalenesulfonamide (W-7) results in novel derivatives with increased inhibitory activities against calcium/calmodulin complex.

A useful calmodulin (CaM) antagonist, N-(6-aminohexyl)-5-chloro-1-naphthalenesulfonamide (W-7), was invented by Hidaka et al. in 1978 (J. Pharmacol.

Studies on the biological activity of tocotrienols.

Tocotrienols were evaluated for activity against transplantable murine tumors inoculated i.p. into mouse, and the activities of two tocotrienols and alpha-tocopherols were compared.

[Potentiation of combination effect of cisplatin and radiation--application of biological response modifiers].

The combination antitumor effect of three kinds of biological response modifiers (lentinan, PSK and juzentaiho-to) was evaluated in the treatment of IMC solid carcinoma with CDDP (9 mg/kg) and/or radiation (1000 rad). Remarkable antitumor effects were observed in the lentinan (2 mg/kg, daily) group to which a single dose of CDDP was given 24 hours before irradiation. On the other hand, combined therapy with CDDP and radiation alone showed less antitumor effect.

[Potentiation of the therapeutic effect of chemotherapy and hyperthermia on experimental tumor and reduction of immunotoxicity of mitomycin C by juzen-taiho-toh, a Chinese herbal medicine].

Potentiation of the therapeutic effects of chemotherapy and local hyperthermia by the Chinese herbal medicine, Juzen-Taiho-Toh (JTX, TJ-48), was studied using murine tumours. Mouse sarcoma 180 tumor cells were inoculated s. c.
