Irradiation of suspensions of Escherichia coli and TiO[sub 2] (anatase) with UV-visible light of wave-lengths longer than 380 nm resulted in the killing of the bacteria within minutes and oxygen was found to be a prerequisite for the bactericidal properties of the photocatalyst.
Coumarins and antiplatelet constituents from the root bark of Zanthoxylum schinifolium.
Among the isolates, terpenyl-coumarins and furoquinolines were the active constituents with antiplatelet aggregation in vitro and collinin showed significant anti-HBC DNA replication activity.

The results suggest that earlier conclusions regarding the effect of the regulatory metal ion on the activity of LAP may have been misleading and casts doubt as to whether the term "regulatory site" has validity in the context of Lap-catalyzed reactions under physiological conditions.

The correlation between the sequence of subtilisin propeptides and their inhibition abilities on the proteases are compared and discussed and pro-Carlsberg behaves as a typical rapid equilibrium competitive inhibitor for these two proteases.
Cytotoxic butanolides from the stem bark of Formosan Lindera communis.
Two new butanolides, lincomolides A and B, were isolated from the chloroform-soluble portion of the stem bark of Lindera communis and exhibited cytotoxicity against P-388 cancer cell lines and showed marginal activity against HT-29.
Anti-platelet aggregation constituents from Gynura elliptica.
