I first encountered purine metabolism research when I worked at the Teikyo University School of Medicine. I completed my doctoral studies by applying the measurement of 5'-methylthioadenosine (MTA), a source of adenine, to clinical cases. As part of research into hyperuricemia and gout, which are related to purine metabolism, we established a method for measuring the purine content in foods and reported the amounts of purine in many foodstuffs together with previous values. That research project was largely due to the dedication of students working on their graduation research after moving to the Faculty of Pharmacy. The resulting analytical data are included in treatment guidelines for hyperuricemia and gout, and are used as reference values in lifestyle guidance, especially dietary therapy, for actual patients. Furthermore, we performed micro-analysis of urinary stones, which are a common complication in patients with hyperuricemia and gout. In urinary stones, proteins related to inflammation and immunity were commonly detected, as well as proteins that differed depending on the type of stone, indicating different formation processes. I hope that the results of these research projects can be used to benefit society.</p>","PeriodicalId":23810,"journal":{"name":"Yakugaku zasshi : Journal of the Pharmaceutical Society of Japan","volume":"145 6","pages":"539-551"},"PeriodicalIF":0.3,"publicationDate":"2025-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144200204","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

When functional food ingredients are poorly water-soluble, they largely fail to be absorbed due to their low solubility in the digestive tract, limiting their ability to exert their functions. To develop poorly water-soluble compounds into viable functional food ingredients, it is important to increase their gastrointestinal absorption so that they can fully exert their functions, and to ensure their safety and efficacy through ADMET research. β-Carotene exerts physiological activities including antioxidant effects, and functions as a source of vitamin A, but it is completely insoluble in water, so it is poorly absorbed from the digestive tract, rendering it difficult to use efficiently as a functional food ingredient. To overcome this problem, we are conducting research on drug delivery system to improve β-carotene solubility and thereby improve its digestive absorption by applying our unique amorphous solid dispersion production technology. To date, we have produced amorphous solid dispersions with dramatically improved water solubility by adding polymers and emulsifiers to β-carotene and kneading these mixtures under heat. The resultant amorphous solid dispersion showed unprecedentedly high gastrointestinal absorption, enhanced inhibition of allergic dermatitis, and enhanced amelioration of cognitive impairment.

Prophylactic supplementation with vitamin B<sub>12</sub> and folic acid reduces hematotoxicity associated with pemetrexed. Metformin, the antidiabetic agent, has been associated with the potential side effect of vitamin B<sub>12</sub> deficiency. This retrospective observational study aimed to evaluate the effect of concomitant metformin use on hematologic adverse events in patients with NSCLC undergoing pemetrexed-based chemotherapy using the Medical Data Vision Database. Patients with stage III or higher NSCLC who received pemetrexed from April 2008 to May 2021 were categorized into metformin-treated (MTF) and non-metformin-treated (non-MTF) groups. The primary outcome was the proportion of granulocyte colony-stimulating factor (G-CSF) administration during cycle (C) 1 to C2 or C2 to C3 of pemetrexed therapy. Propensity score matching (PSM) was used to balance the baseline characteristics between the groups. A total of 1174 patients met the inclusion criteria (54 in MTF and 1120 in non-MTF). After PSM, 52 patients were included in each group. The median metformin dosage in the MTF group was 500 mg/d before and 625 mg/d after PSM. There were no significant differences between the MTF and non-MTF groups in G-CSF administration (15.4 vs. 21.2%, p=0.446). Multivariate logistic regression analysis also showed that metformin use did not significantly affect hematologic toxicity (odds ratio: 1.208, 95% CI: 0.554-2.634).

The work is categorized into following three areas: (1) Evaluation of the bitterness of oral medications using a taste sensor, (2) Development of drug delivery systems utilizing poly(lactic-co-glycolic acid) (PLGA), and (3) Clinical pharmaceutical evaluation of various injectable formulations. In section (1), the bitterness of oral medications, both alone and in combination with food or beverages, was quantitatively assessed. The taste sensor demonstrated high predictive accuracy, with a significant correlation observed between the sensor's bitter-sensitive outputs and the human taste receptor hT2R14, as documented in BitterDB. Recently, an innovative taste sensor featuring lipid/polymer membranes modified with 2,6-dihydroxybenzoic acid (2,6-DHBA), based on an allosteric mechanism, was developed to improve the detection of bitterness in non-charged compounds. In section (2), PLGA microspheres were engineered for the sustained release of prostaglandin derivatives over one month. Furthermore, polymeric micelles under 100 nm in diameter, composed of PLGA and LL-12 (a mutated fragment of human cathelicidin peptide), exhibited potent antibacterial activity and inhibited the proliferation of various cancer cells. Section (3) focuses on injectable formulations, including the development of a quantitative predictive system to evaluate the risk of insoluble particle formation when mixing ceftriaxone with calcium-containing injections. Additionally, the use of minimum inhibitory concentration (MIC) values and nomograms was explored to predict the clinical efficacy of imipenem derivatives.
