Abstract

Background: Therapeutic applications of Fuzi (lateral root of Aconitum carmichaeli Debx) are seriously concerned with its toxic effects. Strategies and approaches to reducing toxicity are of great interest.

Purpose: We aimed to characterize the diurnal rhythm of Fuzi toxicity, and to determine the role of metabolism and pharmacokinetics in generating toxicity rhythmicity.

Methods: Toxicity was determined based on assessment of heart injury and animal survival after dosing mice with Fuzi decoction at different circadian time points. Circadian clock control of pharmacokinetics and toxicity was investigated using Bmal1-deficient (Bmal1-/-) mice.

Results: Fuzi exhibited a diurnal rhythmicity in cardiotoxicity (reflected by plasma CK-MB and LDH levels). The highest level of toxicity was observed at ZT10 (5 PM), while the lowest level of toxicity occurred at ZT22 (5 AM). Also, a higher mortality rate was observed at ZT10 and lower mortality rates at other times of the day. ZT10 dosing of Fuzi generated higher systemic exposures of three toxic alkaloid ingredients aconitine (AC), hypaconitine (HA) and mesaconitine (MA) compared to ZT22. This was accompanied by reduced the formation of the metabolites (N-deethyl-AC, didemethyl-HA and 2?hydroxyl?MA) at ZT10. Bmal1 ablation resulted in an increased level of Fuzi toxicity at ZT22, while having no influences when drug was dosed at ZT10. As a consequence, circadian time-dependent toxicity of Fuzi was lost in Bmal1-deficient mice. In addition, Bmal1 ablation increased the plasma concentrations of AC, HA and MA in mice after oral gavage of Fuzi, and reduced formation of their metabolites (N-deethyl-AC, didemethyl-HA and 2?hydroxyl?MA). Moreover, Fuzi metabolism in wild-type liver microsomes was more extensive at ZT22 than at ZT10. Bmal1 ablation abrogated circadian time-dependency of hepatic Fuzi metabolism.

Conclusions: Fuzi chronotoxicity in mice was attributed to time-varying hepatic metabolism and systemic exposure regulated by circadian clock. The findings may have implications in reducing Fuzi toxicity with a chronotherapeutic approach

Abstract

The unintentional ingestion of toxic compounds in herbs is not uncommon in many parts of the world. To provide timely and life-saving care in the emergency department, it is essential to develop a point-of-care analytical method that can rapidly identify these toxins in herbs. Since electrospray laser desorption ionization mass spectrometry (ELDI/MS) has been successfully used to characterize non-volatile chemical compounds without sample preparation, it was used to identify toxic herbal compounds in this study. The herbal toxins were collected either by sweeping a metallic probe across the surface of a freshly cut herb section or by directly sampling extracts of ground herbal powder. The analytes on the probe were then desorbed, ionized and detected using ELDI/MS, wherein analysis of the herbal toxins was completed within 30 s. This approach allows for the rapid morphological recognition of herbs and early point-of-care identification of herbal toxins for emergency management and is promising in providing important toxicological information to ensure appropriate medical treatment.

Abstract

Over-representation together with deep sequencing can dramatically shorten the discovery process, distinguish aptamers having a wide range of affinity for the target, allow an exhaustive search of the sequence space within a simplified library, reduce the quantity of the target required, eliminate cycling artifacts, and should allow multiplexing of sequencing experiments and targets.
