  • CJC-50100 is a recombinant hepatitis B virus surface antigen (HBsAg) expressed in yeast. The general pharmacological properties of CJC-50100 were evaluated in mice, rats, dogs and isolated guinea pig ileum. The doses were 0.33~33.3 $\mu$g/kg i.m. for mice and rats and 3.3~9.9 $\mu$g/kg i.v. for dogs. The concentrations of 0.002~0.02 $\mu$g/ml were used for the assay with guinea pig ileum. Intramuscular administration of CJC-50100 at the doses did not alter general behavior and the responses for central nervous system, smooth muscle, gastrointestinal system, cardiovascular and respiratory system, and water and electrolytes excretion. In summary, CJC-50100 had no pharmacological effect in these studies even up to the 100-fold of the expected clinical dose, 20 $\mu$g/man/60 kg.

  • The solution-phase combinatorial synthesis of iminodiacetic acid triamide libraries linked to 1-(4-chlorobenzhydryl)piperazine has been reported. Ten mixture libraries, each containing 5 components, were synthesized in 4 steps from N-BOC-iminodiacetic acid anhydride. Antibradykinin effects of the mixture and individual libraries were compared using guinea-pig ileum smooth muscle. The changes in the inhibition were also observed by testing the combination of two different compounds from the same library. We found out the correlation between the inhibition of mixtures and that of individual libraries. It is possible to choose the mixtures with relatively high inhibitory effects to find out the most effective individual compound for further synthesis.

  • CJ-50001 is a recombinant granulocyte-colony stimulating factor (rG-CSF) synthesized by recombi-nant DNA technology using E. coli as an expression system. The general pharmacological properties of CJ-50001 were evaluated in mice, rats, dogs and isolated guinea pig ileum. The doses are 100, 300 and 1, 0007g/kg, i.v. for mice and rats, 1, 10 and 100$\mu$g/kg, 1.v. for dogs and 1 and 10$\mu$g/ml for isolated guinea pig ileum. Intravenous administration of CJ-50001 at this dose range did not affect general behavior, central nervous system, smooth muscles, gastrointestinal system, cardiovascular and respiratory system and water and electro-lytes excretion. In summary, CJ-50001 had no harmful pharmacological erect in these studies even up to the 200-fold expected clinical dose, 2507g/man.

  • General pharmacological properties of ι-muscone, the major component of musk, were investigatedin mice, rats and guinea pig. The administration of ι-muscone (1, 10, 100 mg/kg, p.o.) in mice had no effects in general behaviors, and no influences on analgesic actions and normal body temperature. Muscle relaxant action, intestinal propulsion and gastric secretion were not observed even at the high dose of 100 mg/kg. ι-Muscone (1, 10, 100 mg/kg, p.o.) given to conscious rats showed no effect on mean blood pressure and heart rate. It showed no direct effect at 2.4$\times$10.3 mg/ml and 2.4$\times$10-2 mg/ml in isolated uterus of rats and ileum of guinea pig, and also had no inhibition of contraction induced by oxytocin and histamine.

  • Effects of endothelin-l (ET-l) on contraction, $Ca^{2+}$ transient and L -type $Ca^{2+}$ current ( $I_{Ca,L}$) were investigated in single ventricular myocytes isolated from guinea-pig hearts. ET-l at concentrations of 5 and 10 nM produced a biphasic pattern of inotropism: a first decrease in contraction by 34.4$\pm$2.5 % of the control followed by a sustained increase in contraction by 66.6$\pm$8.4% (mean$\pm$S.E.M., n=9).(omitted)

  • Aspalatone [3-(2-methyl-4proponyl)]-2-acetyloxybenzoate, CAS 147249-33-0) is a compound having an antithrombotic action. General pharmacological properties of aspalatone were studied. Aspalatone had no effect on central nervous system and no anticonvulsant effect up to 1200 mg/kg p.o. However, the compound has hypothermic and analgesic effect. When administered intravenously in rabbits, aspalatone did not affect blood pressure, heat rate and respiration rate and depth, and it did not inhibit transient hypotensive effect of acetylcholine. The compound did not affect isolated guinea-pig ileum and tracheal strip at a concentration of 1${\times}$$10^{-4}$, and did not inhibit histamine-induced contraction of guinea-pig ileum. It also did not affect isolated rat stomach fundus and estrogenated rat uterus at 1${\times}$$10^{-4}$, and did not inhibit contraction produced by acetylcholine or oxytocin. The pupil size and intestinal propulsion were not influenced at a large dose of was shown. The compound showed a slight increase in urine volume and led to decreased excretion of potassium in urine of rats. The results suggest that aspalatone may have no considerable adverse effects in general pharmacological aspect.

  • A series of N,N'-substituted iminodiacetamide derivatives was synthesized and evaluated their inhibitory effects on the histamine-induced smooth muscle contraction in guinea-pig ileum and on the histamine release from IgE-sensitized RBL-2H3 cells (rat basophilic leukemia cell line). Compounds A3, A4 and A5 which have 1-(4-chlorobenzhydryl) piperazine moiety, showed both moderate antihistamine activity and histamine release inhibitory activity.

  • Effects of eight flavonoids and their related compounds on leukocytes migration, superoxide anion production and lipid peroxidation in the phagocytosis of latex beads or E. coli by guinea pig peritoneal exudate cells were studied in vitro. It shows that most of flavonoids generally inhibited the leukocytes migration and production of superoxide anion and malonedialdehydes. Their inhibitory activities in the phagocytosis of latex beads had more active than that of E. coli. Quercetin has the most inhibitory activity in leukocytes migration and production of superoxide anion and lipid peroxides at the concentration of 1, 2 and 10 $\mu{M}$. Catechin and rutin at the concentration of 2 and 10 $\mu{M}$ inhibited significantly the production of superoxide anion and lipid peroxides. Flavone, catechin, naringin and rutin at the concentration of 2 and 10 $\mu{M}$ inhibited significantly the leukocytes migration.

  • Eye irritation, primary skin irritation and skin sensitization tests for Aloewhite were tested in New Zealand White rabbits and Hartley guinea pig. In primary skin irritation test of male New Zealand White rabbits, body weights were not significantly changed and Primary Irritation Index (PII) was O.47, indicating Aloewhite as mildly irritating material. In ocular irritation test, any injury on iris, conjunctival membrane, and cornea in New Zealand White rabbits was not observed. No injuries of the ocular mucous membrane were also recorded. Skin sensitization was tested in guinea pig after intradermal and epicutaneous induction and graded 1 with zero % sensitization rate. These results indicate that Aloewhite was not considered to be irritant in test organs of animals.
