[Synthesis and cardiovascular activities of peptidyl dopamine derivatives].

Amino acids and small peptides with different steric configurations and lipophilicities were appended to dopamine. Eighteen compounds have been synthesized. The attachment of D-amino acids or N-methyl amino acids onto the dopamine molecule caused a marked decrease in cardiovascular activity by intravenous injection, while the introduction of lipophilic amino acids caused a marked increase in myocardial contractility and blood pressure in anesthetized dogs. The durations of action were also prolonged.

Effects of matrix metalloproteinase inhibitor BB-94 on liver cancer growth and metastasis in a patient-like orthotopic model LCI-D20.

BACKGROUND/AIMS: The aim of this study was to try to understand the effects of the synthetic matrix metalloproteinase inhibitor Batimastat (BB-94) on hepatocellular carcinoma (HCC). METHODOLOGY: An orthotopic metastatic human hepatocellular carcinoma in nude mice model (LCI-D20) was used to study primary tumor growth, local invasion and metastasis of HCC. MTT assay was used to study the effects of BB-94 on cytotoxin and proliferation of HCC cell line SMMC-7721 in vitro. A gelatine zymograph was used to study the expression of MMPs in the LCI-D20 tumor tissue. RESULTS: BB-94 can inhibit primary tumor growth, local invasion, intrahepatic and lung metastasis, as well as prolong survival. BB-94 did not affect the proliferation of HCC cells in vitro. LCI-D20 tumor tissue expresses MMP-2 and MMP-9. CONCLUSIONS: BB-94 has a cytostatic therapeutic effect on HCC.
