The Applications of qNMR in Drug Quality Control
Yakugaku Zasshi. 2024;144(4):381-385. doi: 10.1248/yakushi.23-00151-6.ABSTRACTNMR is well known as one of the most important methods for elucidating the structure of organic compounds. Furthermore, it has recently been recognized as a powerful tool for quantitative analysis. The quantitative NMR (qNMR) has become an official analytical method described in detail in the Japanese Pharmacopoeia. And today, it is widely applied in drug development. The qNMR method offers many new advantages over traditional and conventional quantitative analysis methods. For example, this method requires only a few milligrams of the analyte an...

Dissemination of Information from Basic Research on Aging: Species, Strain, Substrain and Sex Differences
Yakugaku Zasshi. 2024;144(4):389-395. doi: 10.1248/yakushi.23-00165-1.ABSTRACTVarious organisms with different lifespans such as yeast, nematodes, fruit fly, mice, and rats are used for basic research on mechanisms of aging and anti-aging. These organisms are often genetically engineered and used to elucidate the contribution of certain genes to aging. For example, genetic recombination techniques revealed that the lifespan of superoxide dismutase (SOD) transgenic flies extended up to approximately 30%. This result suggests that increasing antioxidant capacity extends lifespan possibly by reducing oxidative damage. However...

Aging-associated Cyst Formation and Fibrosis
Yakugaku Zasshi. 2024;144(4):397-402. doi: 10.1248/yakushi.23-00165-2.ABSTRACTCysts are abnormal fluid-filled sacs found in various human organs, including the liver. Liver cysts can be associated with known causes such as parasite infections and gene mutations, or simply aging. Among these causes, simple liver cysts are often found in elderly people. While they are generally benign, they may occasionally grow but rarely shrink with age, indicating their clear association with aging. However, the mechanism behind the formation of simple liver cysts has not been thoroughly investigated. Recently, we have generated transgeni...

Regulation of Aging Processes: A Perspective of Dietary Restriction Models
Yakugaku Zasshi. 2024;144(4):403-409. doi: 10.1248/yakushi.23-00165-3.ABSTRACTThe moderate restriction of dietary energy intake (dietary restriction: DR) extends the lifespan and health span of various laboratory animals, suggesting that it delays the aging process inherent in many animal species. Attenuated growth hormone and insulin-like growth factor-1 (IGF-1) signaling caused by mutations also increases the lifespan of mice, even those allowed to feed freely. In nematodes, the Daf16, mammalian Forkhead box O (FoxO) transcription factor, was shown to be required for lifespan extension in response to reduced IGF-1 signal...

Regulation of Aging and Lifespan by White Adipose Tissue
Yakugaku Zasshi. 2024;144(4):411-417. doi: 10.1248/yakushi.23-00165-4.ABSTRACTLong-term caloric restriction (CR) is an effective intervention that improves whole-body metabolism, suppresses age-related pathophysiology, and extends lifespan. Although the beneficial effects of caloric restriction mediated by growth hormone/insulin-like growth factor-1 (GH/IGF-1) have been extensively studied, the mechanisms independent of GH/IGF-1 remain largely unknown. In this review, we focus on these GH/IGF-1-independent mechanisms, with a particular emphasis on the role of sterol regulatory element-binding protein 1c (SREBP-1c). CR incr...

Is Biological Aging a Treatable Disease? A Consideration Based on Proposed Mechanisms of Aging
Yakugaku Zasshi. 2024;144(4):419-429. doi: 10.1248/yakushi.23-00165-5.ABSTRACTIn view of the current claim by many researchers that biological aging is a treatable disease, the possibility is discussed whether the claim is realistic, based on several proposed mechanisms of aging. The definition of biological aging is stated referring to physiological aging and pathological aging, since biological aging must be defined for the discussion of whether it can be cured. Aging in animal model is compared with that in humans in terms of common age-associated phenotypes. Major proposed mechanisms of aging are next examined includin...

Evaluation of the Simple Suspension Method for Oral Anticancer Drugs
Yakugaku Zasshi. 2024;144(4):441-445. doi: 10.1248/yakushi.23-00194.ABSTRACTThe simple suspension method (SSM) involves administering tablets or capsules using a tube after disintegration and suspension in hot water without crushing or opening the capsule. Particularly, for anticancer drugs, it is an excellent method of administration that reduces the risk of exposure during dispensing. In contrast, information on SSM for individual drugs is insufficient. Anticancer drugs present a therapeutic challenge because their information is limited. We investigated whether SSM is possible with 36 anticancer drugs. Furthermore, we e...

Examination of Analytical Method for Tris(2,3-dibromopropyl)phosphate and Bis(2,3-dibromopropyl)phosphate to Revise the Official Methods Based on "Act on the Control of Household Products Containing Harmful Substances"
In this study, the validity of the developed test method is evaluated at six laboratories using two types of textile samples spiked with TDBPP and BDBPP at three concentrations (4, 8, and 20 µg/g). TDBPP and BDBPP are extracted under reflux using methanol containing hydrochloric acid. TDBPP is analyzed using GC-MS, and BDBPP is also analyzed using GC-MS after methylation with trimethylsilyl diazomethane. Although the accuracy (70-120%), repeatability (<10%), and reproducibility (<15%) of a few samples, mainly low concentration samples, are out of range, overall, the concentration level of detection limits of TDBPP a...

Evaluation of Contractile Function Using Human iPS Cell-derived Cardiomyocytes
Yakugaku Zasshi. 2024;144(3):251-255. doi: 10.1248/yakushi.23-00164-1.ABSTRACTCardiotoxicity induced by anti-cancer drugs is a significant concern for patients undergoing cancer treatment. Some anti-cancer drugs can damage cardiac muscle cells directly or indirectly, potentially leading to severe heart failure. Various risk factors, including the type and dosage of chemotherapy agents as well as patient background, contribute to the development of cardiotoxicity. Human-induced pluripotent stem cell-derived cardiomyocytes (hiPSC-CMs), which enable patient-specific toxicity prediction, hold great promise in this regard. Howe...

Development of Preventive Methods for Drug-induced Cardiotoxicity Using a Large-scale Medical Information Database
Yakugaku Zasshi. 2024;144(3):257-264. doi: 10.1248/yakushi.23-00164-2.ABSTRACTCancer therapies have evolved considerably thereby substantially improving the survival of patients with cancer. However, cardiotoxicity, such as myocarditis and heart failure, induced by anticancer drugs, including immune checkpoint inhibitor(ICI)s and doxorubicin, present serious challenges. Numerous observations have indicated increased risks of cardiotoxicity- and cancer-related mortality in patients with drug-induced cardiotoxicity. Therefore, the prevention and management of drug-induced cardiotoxicity should be prioritized to enable sustai...

Prediction of Cardiac Toxicity by Anti-cancer Drugs Using iPSC Cardiomyocytes
Yakugaku Zasshi. 2024;144(3):265-271. doi: 10.1248/yakushi.23-00164-3.ABSTRACTRecent advances in cancer therapy have significantly improved the survival rate of patients with cancer. In contrast, anti-cancer drug-induced adverse effects, especially cardiotoxicity, have come to affect patients' prognosis and quality of life. Therefore, there is a growing need to understand the anti-cancer drug-induced cardiotoxicity. Human induced pluripotent stem (iPS) cell-derived cardiomyocytes (hiPSC-CMs) have been used to assess drug-induced cardiotoxicity by improving the predictability of clinical cardiotoxicity and the principles of...
