“证候”是中医学辨证论治的理论基石,证候的表型组学研究是回答中医药科学性问题的关键环节。肾虚证在临床各科疾病中极为常见,但其客观化研究仍存在物质基础认识模糊、评价标准不完备等难点。代谢组学符合中医学“整体观念”特征,为揭示证候理论实质提供新视角,可较好地结合系统生物学与中医证候。本文梳理肾虚致病的复杂性、多样性与机体代谢网络失稳的相关性,认为氨基酸代谢、菌群代谢及能量代谢紊乱等是中医肾虚证的微观物质体现,且不同疾病的同一证型、同一证型不同表型间的内源性代谢产物均具备良好鉴别效应与诊断价值,可为进一步阐释中医证候学特征、肾虚证实质认识及客观评价研究提供参考。

Chinese Chemical Letters 2019年第1期30卷 247-249页

Eight new water-soluble amino acid conjugates 6 a-h of chlorin p6 ethers(5 a-d) were synthesized and preliminarily investigated for their in vitro PDT antitumor activity and structure-activity relationship(SAR). The results showed that all compounds exhibited much higher phototoxicity against tumor cells than talaporfin. SAR analysis indicated that PDT antitumor effect enhanced with the increase of carbon chain length of alkoxyl ether bonds at 3~1-position, and L-aspartic acid was superior to L-glutamic acid. In particular, the IC_50 values of most phototoxic compound 6 d were 0.20 mmol/L against A549 cell and0.41υmmol/L against B16-F10 cell, which individually represented 31-and 24-fold increase of antitumor potency compared to talaporfin, suggesting that it was a promising candidate photosensitizer(PS) for PDT applications due to its strong absorption at long wavelength, high phototoxicity, low dark cytotoxicity and good water-solubility.
