  • The purpose of this research was to investigate the immunoregulatory effect, apoptosis of L 1210 leukemia cells of Comus officinalis Sieb.et Zucc. The proliferation of cultured splenocytes and thymocytes were enhanced by the addition of SSY. Splenic, thymic and mesenteric lymph node-T lymphocytes, especially TH cells was significantly increased in SSY-administered (p.o. for 7 days) mice. SSY treatment induced the apoptosis of L1210 mouse leukemia cells. In addition, SSY accelerated the phagocytic activity and nitric oxide production in peritoneal macrophages. These results suggest that SSY have an immuno-regulatory property and anti-cancer effect.

  • An attempt was made to develop new water-soluble antitumor Pt(ll) complexes containing ethylenediamine, and their structures were determined by infrared spectroscopy, $^{13}C$ nuclear magnetic resonance and elemental analysis. Their antitumor activities in vitro against L-1210, p-388 leukemia cells and M-14 melanoma cells were investigated and acceptable antitumor activity was found as compared with cisplatin.

  • The purpose of this research was to investigate the effect of Cheongsimondam-tang(CSODT) on the activity of immune cell and anti-carcinogenic effect of mouse leukemia cell. The addition of CSODT(1 ㎍/ml) enhanced the proliferation of cultured-splenocytes and thymocytes. And also administration of CSODT(500 ㎍/kg) accelerated subpopulation of splenic and thymic T lymphocytes especially CD4/sup +/-T/sub H/ cells in BALB/c mice. CSODT treatment decreased cell proliferation and increased apoptotic cell death of cultured-L1210 leukemia cells, and induced apoptosis in addition to decreased mitochondrial transmembrane potential (ΔΨm) of transplanted-L1210 cells in vivo. These results suggest that CSODT have a cellular immuno-regulatory effect and anti-cancer property action.

  • This study was conducted to investigate the immuno-regulatory effect and apoptosis of L1210 and HL60 leukemia cells of methanol-extracts of Cornus kousa Burg(CKB). The proliferation of mouse splenocytes and thymocytes enhanced by the addition of $10\;{\mu}g/ml$ of CKB. CKB were administered p.o. once a day for 7 days in adult male BALB/c mice. CKB increased the splenic and thymic T lymphocytes, especially the number of $T_H$ cells markedly increased by the treatment of CKB. CKB treatment induced the apoptotic cell death in L1210 mouse leukemia and HL60 human leukemia cells. In addition, CKB also accelerated the phagocytic activity in peritoneal macrophages and increased the production of plaque forming cells. These results suggest that CKB have an various immuno-regulatory property.

  • In order to find out a proper connecting bridge between 5-fluorouracil(5-FU) and a macromolecule such as a polypeptide, potentially hydrolytic N$^{1}$-derivartives of 5-FU have been systhesized and evaluated for their biological activity. When tested with in vitro leukemic L$_{1210}$ cells all the obtained derivartives exhibited slightly higher antitumor activity than the parent 5FU. Among them the N$^{1}$ -carbamoyl analogue 2 and N$^{1}$-acetamido analogue 6b showed 50% inhibition of the L$_{1210}$ cell growth at the concentrations of 5.01$\times$10$^{-8}$M and 1.03$\times$10$^{-7}$M, respectively. When tested against sarcoma 180 tumor cells inoculated into mice, the compounds 2 and 6b exhibited, respectively, 62% and 54% inhibition of the solid tumor growth at the 5-time doses of 100 mg/kg/day. Both compounds, N$^{1}$-carbamoyl analogue 2 and N$^{1}$-acetamido analogue 6b, realeased the parent 5-FU when incubated in the L$_{1210}$ cell cultural media for 5 hrs.

  • 오미자의 면역조절작용에 미치는 효과를 살펴본 결과, 오미자(SZX)는 T 및 B세포의 증식을 유의성있게 촉진시켰으며, in vivo 및 in vitro 실험에서 비장내의 T 및 B림프구를 증가시켰고, T세포 중 특히 $T_H$세포를 증가시켰다. 또한 흉선 T림프구 중의 $T_H$세포의 수를 증가시키는 작용을 나타냈다. 아울러 SZX는 in vitro계에서 L1210세포의 apoptosis를 유도하였으며, 복강대식세포에서의 탐식능 및 nitric oxide(NO)생성을 촉진시켰다. 이 결과는 복강대식세포로부터 생성된 NO가 L1210세포의 apoptosis를 유도하는데 중개역할을 하고 있을 가능성을 시사한다. 이상의 결과 오미자는 T, B림프구 및 대식세포 등의 면역세포의 활성을 증강시키는 작용을 보유하고 있으며, 암세포의 apoptosis를 유도하는 기능을 가지고 있음으로써 면역조절제로서의 역할을 가지는 것으로 추정된다.

  • As part of a research program to develope 3rd generation anti tumor platinum complexes, a series of platinum complexes which have 4, 5-bis-(aminomethyl)- 1, 3-dioxolane derivatives as bidenate amine ligands, represented by the general structual formula was prepared. The R$_1$ and/or R$_2$ substituents in this series of platinum complexes can be hydrogen. alkyl, of jointly formed cyclohexane. Two Xs can be a bidenate leaving ligand such as 1, 1-cyclobutanedicarboxylate, malonate, dimethylmalonate, ethylmalonate, glycolate, L-lactate, or N-methyliminodiacetate. From based on the pharmacological and toxicological studies, we have chosen SKI 2053R, cis-malonato[(4R, 5R)-4, 5-bis(aminomethyl)-2-isopropyl-1, 3-dioxolane] platinum(II) complex (NSC D644591) as a candidate for clinical evaluation. The antitumor activity of a new anti tumor platinum complex, cis-malonato [(4R, 5R)-4, 5-bis(aminomethyl)-2-isopropyl-1, 3-dioxolane] platinum(II) (SKI 2053R, NSC D644591), was compared with those of cisplatin and carboplatin using murine tumors. We evaluated three platinum complexes against L1210/CPR, a subline of L1210 leukemia resistant to cisplatin for their abilities to overcome tumor resistance to cisplatin. The in vitro cytotoxicity of SKI 2053R to L1210 cell line was 2.5-fold less potent thann that of cisplatin, and was 10-fold more cytotoxic than that of carboplatin. SKI 2053R retained similar cytotoxic effect and anti tumor activity to L1210/CPR cell line, like the cytotoxicity of SKI 2053R to L1210 cell line, while either cisplatin or carboplatin had not property to overcome the acquired cisplatin-resistance. SKI 2053R exhibited greater or comparable antitumor activity than cisplatin or carboplatin in murine tumor models.
