Dimethylarsenate [DMAs(V)] can be produced by some soil microorganisms through methylation of inorganic arsenic (As), especially in anoxic paddy soils. DMAs(V) is more phytotoxic than inorganic As and can cause the physiological disorder straighthead disease in rice. Rice cultivars vary widely in the resistance to DMAs(V), but the mechanism remains elusive. Here, we investigated the differences in DMAs(V) uptake, translocation, and reduction to dimethylarsenite [DMAs(III)], as well as the effects on the metabolome, between two rice cultivars Mars and Zhe733. We found that Mars was 11-times more resistant to DMAs(V) than Zhe733. Mars accumulated more DMAs(V) in the roots, whereas Zhe733 translocated more DMAs(V) to the shoots and reduced more DMAs(V) to DMAs(III). DMAs(III) was more toxic than DMAs(V). Using heterologous expression and in vitro enzyme assays, we showed that the glutathione-S-transferases OsGSTU17 and OsGSTU50 were able to reduce DMAs(V) to DMAs(III). The expression levels of OsGSTU17 and OsGSTU50 were higher in the shoot of Zhe733 compared to Mars. Metabolomic analysis in rice shoots showed that glutathione (GSH) metabolism was perturbed by DMAs(V) toxicity in Zhe733. Application of exogenous GSH significantly alleviated the toxicity of DMAs(V) in Zhe733. Taken together, the results suggest that Mars is more resistant to DMAs(V) than Zhe733 because of a lower root-to-shoot translocation and a smaller capacity to reduce DMAs(V) to DMAs(III).

Abstract:

Darinaparsin is a novel organic arsenical compound of dimethylated arsenic conjugated to glutathione, with antitumor activity and a mechanism of action markedly different from other available agents. This phase 2, nonrandomized, single-arm, open-label study evaluated the efficacy and safety of intravenous darinaparsin (300 mg/m2 over 1 hour, once daily for 5 consecutive days, per 21-day cycle) and its pharmacokinetics at multiple doses in 65 Asian patients with relapsed or refractory peripheral T-cell lymphoma (PTCL). The primary end point was the overall response rate (ORR). The ORR based on central assessment was 19.3% (90% confidence interval, 11.2-29.9), which was significantly higher than the predefined threshold of 10% (P = .024). The ORR was 16.2% in patients with PTCL–not otherwise specified and 29.4% in patients with angioimmunoblastic T-cell lymphoma. Tumor size decreased in 62.3% of patients. Treatment-emergent adverse events (TEAEs) were observed in 98.5% of patients. Grade ≥3 TEAEs with an incidence rate of ≥5% included anemia (15.4%), thrombocytopenia (13.8%), neutropenia (12.3%), leukopenia (9.2%), lymphopenia (9.2%), and hypertension (6.2%). Darinaparsin is effective and well tolerated, with TEAEs that were clinically acceptable and manageable with symptomatic treatment and dose reductions. This trial was registered at www.clinicaltrials.gov as #NCT02653976.

Brand Institute Partners on Brand Name Development for Treatment of Relapsed or Refractor Peripheral T-Cell Lymphoma Now Approved by Ministry of Health, Labour and Welfare (Japan)

MIAMI, July 5, 2022 /PRNewswire/ -- Brand Institute is proud to announce its work with Solasia Pharma K.K. ("Solasia") in developing the brand name DARVIAS®. DARVIAS®, an organoarsenic compound with anticancer activity, is a novel mitochondrial-targeted agent being developed for the treatment of various hematologic and solid tumors. DARVIAS® provokes cell cycle arrest and apoptosis through disruption of mitochondrial functions and increased production of reactive oxygen species in tumor cells. DARVIAS® is expected to exert an anticancer effect by inducing cell cycle arrest and apoptosis. DARVIAS® has been approved for relapsed or refractory Peripheral T-Cell Lymphoma by Japan's Ministry of Health, Labour and Welfare (MHLW). Japan is the first country in the world where DARVIAS® has been approved. DARVIAS® has been granted orphan drug designation in the US and EU. "The entire Brand Institute and Drug Safety Institute team congratulates Solasia on the MHLW approval of the DARVIAS injection," said Brand Institute's Chairman and C.E.O., James L. Dettore. About Brand Institute and our wholly owned regulatory subsidiary, Drug Safety Institute Brand Institute is the global leader in pharmaceutical and healthcare-related name development, with a portfolio of over 3,800 marketed healthcare brand names, 1,200 USAN/INN nonproprietary names for 1,100 clients. The company partners on over 75% of pharmaceutical brand and nonproprietary name approvals globally every year with healthcare manufacturers. Drug Safety Institute is composed of former naming regulatory officials from global government health agencies, including Food and Drug Administration (FDA), European Medicines Agency (EMA), Health Canada (HC), American Medical Association (AMA), and the World Health Organization (WHO). These regulatory experts co-authored the name review guidelines while with their respective agencies, with many responsible for ultimately approving (or rejecting) brand name applications. Now working for a private company, these professionals provide Brand Institute's clients with industry-leading guidance pertaining to drug name safety (i.e., preventing medication errors), packaging, and labeling.
