Prediction of mitochondrial targeting, or prediction of exclusion from mitochondria, of small-molecule xenobiotics (biocides, drugs, probes, toxins) can be achieved using an algorithm derived from QSAR modeling. Application of the algorithm requires knowing the chemical structures of all ionic species of the xenobiotic compound in question, and for certain numerical structure parameters (AI, CBN, log P, pK , and Z) to be obtained for all such species. Procedures for specification of the chemical structures; estimation of the structure parameters; and application of the algorithm are described in an explicit protocol.

Hepatocellular carcinoma (HCC) is the most prevalent form of primary liver cancer, notoriously refractory to conventional chemotherapy. Historically, sulfane sulfur-based compounds have been explored for the treatment of HCC, but their efficacy has been underwhelming. We recently reported a novel sulfane sulfur donor, PSCP, which exhibited improved chemical stability and structural malleability.

Ferroptosis is a form of iron-dependent programmed cell death, which is distinct from apoptosis, necrosis, and autophagy. Mitochondria play a critical role in initiating and amplifying ferroptosis in cancer cells. Voltage-Dependent Anion Channel 1 (VDAC1) embedded in the mitochondrial outer membrane, exerts roles in regulation of ferroptosis.

Hydrogen sulfide (HS) is an important gasotransmitter that regulates a wide range of pathophysiological processes. Higher uric acid levels are associated with an increased risk of metabolic diseases. The causal mechanism linking HS signalling and uric acid metabolism in skeletal muscles has not yet been elucidated.

Ethnopharmacological Relevance: Xinbao pill (XBP) is a renowned Chinese patent medicine, primarily efficacious in warming and nourishing the heart and kidneys, supplementing Qi to boost Yang, and promoting blood circulation to remove blood stasis. XBP has been utilized for the treatment of chronic heart failure (CHF) for nearly 30 years, but the lack of clarity regarding the active ingredients of XBP against CHF has hindered its clinical application and further promotion.
Aim Of The Study: To comprehensively elucidate the efficacy-specific ingredients and potential mechanism of XBP against CHF.

Frostbite injury refers to cold tissue injury which typically affects the peripheral areas of the body, and is associated with limb loss and high rates of morbidity. Historically, treatment options have been limited to supportive care, leading to suboptimal outcomes for affected patients. The pathophysiology of frostbite injury has been understood in recent years to share similarity with that of cold ischemia-reperfusion injury as seen in solid organ transplantation, of which mitochondria play an important contributing role.
