Synthesis of the ginseng tetrapeptide, 1 and of the configuration and conjugation isomers, H-L-Val-γ-L-Glu-L-Arg-Gly-OH(2), H-L-Val-D-Glu-D-Arg-Gly-OH (3), and H-L-Val-L-Glu-L-Arg-Gly-OH (4) was carried out by a solid-phase method using the Fmoc strategy. The effects of 1-4 on the proliferation of baby hamster kidney (BHK)-21 cells, normal female bronchiogenic epithelioid (CCD-14 Br) cells, and normal human epidermal fibroblast (NB1 RGB) were examined. Only 1 showed 32 and 23% enhancement of BHK-21 and human CCD-14 Br cells growth, respectively, at a concentration of 13.6 μM and 41% enhancement of NB1 RGB cells growth at a concentration of 32 μM under the conditions employed. It was shown that both the configuration of the component amino acids and the peptide conjugation at a γ-position of D-Glu in 1 are important for proliferation of the cells. Compound 1 exerted a prominent effect on cell stimulation and growth rate without any morphological change and showed no cytotoxicity.}, pages = {46--47}, title = {ヒト気管支上皮細胞と上皮センイ芽細胞の成育におよぼす人参テトラペプチドとその異性体}, volume = {16}, year = {1998} }
