Abstract
Adult T-cell leukemia-lymphoma (ATL) is a distinct mature T-cell malignancy caused by human T-cell leukemia/lymphotropic virus type I (HTLV-1) endemic in some areas in the world. HTLV-1 transmits through mother-to-child infection via breastfeeding, sexual intercourses, and blood transfusions. Early HTLV-1 infection, presumably through mother’s milk, is crucial in developing ATL. The estimated cumulative risk of the development of ATL in HTLV-1 carriers is a few percent after transmission from their mothers. The median age of ATL onset is about 70 in Japan and is now rising, whereas an overall mean age in the mid-forties is reported in other parts of the world. ATL is classified into four clinical subtypes (acute, lymphoma, chronic, and smoldering) defined by organ lesions and LDH/calcium values. In aggressive ATL (acute, lymphoma or unfavorable chronic types) and indolent ATL (favorable chronic or smoldering types), intensive chemotherapy followed by allogeneic hematopoietic stem cell transplantation and watchful waiting until disease progression has been recommended, respectively, in Japan. Based on a worldwide meta-analysis and multiple other retrospective studies, the antiviral combination of interferon alpha (IFN) and zidovudine (AZT) is recommended in many parts of the world in acute, chronic, and smoldering ATL whereas patients with the lymphoma subtype are treated with chemotherapy, either alone or combined with AZT/IFN. Several new agents have been approved for ATL by the Pharmaceutical and Medical Devices Agency (PMDA) after clinical trials, including an anti-CC chemokine receptor 4 monoclonal antibody, mogamulizumab; an immunomodulatory agent, lenalidomide; and an anti-CD30 antibody/drug conjugate, brentuximab vedotin.

Abstract
Antiretroviral therapy has been the mainstay of treatment for neonates born to HIV infected mothers. Neonates born prematurely to HIV positive mothers are underdeveloped not only in anatomical terms but also in their physiological systems. Zidovudine, the first antiretroviral drug in clinical therapy for the treatment of HIV has been approved for use in preterm neonates both prophylactically and therapeutically. The present work describes the whole body physiologically based pharmacokinetic (WB-PBPK) model development for zidovudine in preterm neonates of varying gestational ages, to observe the pharmacokinetic behavior of the drug in this vulnerable group of the population. Along with the height, weight, post-natal, and gestational ages of the preterm neonates, metabolic enzymes CYP2A6, CYP2C8, etc. were incorporated for each neonate. The composition of the different organs in terms of water and lipid components, blood flow rates, etc. were specified during simulations according to the gestational ages of these neonates. The following PK parameters were estimated for preterm neonates using simulated plasma profiles: AUC 2686.41 ± 123.49 μmol min/L, Cmax 6.46 ± 0.74 μmol/L, half-life 8.98 ± 2.36 hr, mean residence time 12.23 ± 3.43 hr, and total plasma clearance 1.48 ± 0.19 ml/min/kg in comparison with the observed PK parameters of a clinical study by Mirochknic et al. in preterm neonates with AUC 2020.04 μmol/min/L, Cmax 6.10 μmol/L, and total plasma clearance 1.62 ml/min/kg. PBPK simulations provide an opportunity to visualize the possible impact of physiological maturity levels at varying gestational ages on the pharmacokinetic behavior of zidovudine in preterm neonates.

Abstract
In this study, an intravaginal delivery system able to deliver an anti-HIV-1 agent for the purpose of potentially reducing HIV-1 transmission acting over an extended duration was successfully formulated. This delivery system was a composite polymeric caplet comprising zidovudine-loaded polyethylene glycol enclatherated pectin-mucin submicron matrices embedded within a poly (D,L-lactide), magnesium stearate, Kollidon® SR, and Carbopol® 974P NF-based polymeric caplet matrix. A three-factor and three-level Box-Behnken statistical design was utilized to optimize the polymeric caplet. The optimized directly compressed composite polymeric caplet hardness was 22.1 ± 0.3 N and the matrix resilience was 62.4 ± 0.6%. The swelling- and diffusion-controlled fractional zidovudine (AZT) release from the optimized caplet was 0.74 ± 0.01 in simulated vaginal fluid (SVF), which increased to 0.81 ± 0.21 in phosphate-buffered saline (PBS) simulating seminal fluid, over 30 days. Caplet matrix swelling was directly related to the percentage Carbopol 974P NF composition. An intravaginal system for AZT delivery was tested in the pig model over 28 days. X-ray analysis depicted delivery system swelling with matrix contrast fading over time as vaginal fluid permeated the matrix core. Plasma, vaginal fluid swab eluates, and tissue AZT concentrations were measured by gradient ultra-performance liquid chromatography (UPLC)-tandem photodiode array detection. Vaginal tissue and vaginal fluid swab eluate AZT concentrations remained above effective levels over 28 days and were higher than plasma AZT concentrations, availing a system with reduced systemic toxicity and more effective inhibition of viral replication at the site of entry.

Abstract
BACKGROUND Humans can be frequently exposed to Bisphenol A (BPA) via multiple sources, and babies are considered to be the most sensitive group to exposure of BPA. AIMS To investigate the inhibition potential of BPA towards human liver microsomes (HLMs)-catalyzed zidovudine (AZT) glucuronidation. MATERIALS AND METHODS In vitro HLMs incubation system was used to investigate the inhibition potential of BPA towards AZT glucuronidation. Both Dixon and Lineweaver-Burk plots were employed to determine the inhibition kinetic type, and nonlinear repression was utilized to calculate the inhibition kinetic parameters (Ki). RESULTS Concentration-dependent inhibition of BPA towards AZT glucuronidation was observed. Both Dixon and Lineweaver-Burk plots showed that BPA exerted competitive inhibition towards the glucuronidation of AZT, and nonlinear repression with competitive equation was used to calculate the Ki value to be 3.2 µM. CONCLUSION Potential BPA-AZT interaction might occur when the patients administered with AZT is also exposed to BPA.

Abstract
BACKGROUND Herb-drug interaction (HDI) has been regarded as a key factor limiting the clinical application of herbs and drugs. AIMS Potential baicalein-zidovudine (AZT) interaction was predicted in the present study. METHODS In vitro evaluation of baicalein's inhibition towards human liver microsomes (HLMs)-catalyzed metabolism of zidovudine (AZT) was performed. Dixon and Lineweaver-Burk plots were used to determine the inhibition kinetic type, and second plot with the slopes from Lineweaver-Burk plot versus the concentrations of baicalein was employed to calculate the inhibition parameter (Ki). In combination with the in vivo concentration of baicalein, in vitro-in vivo extrapolation (IVIVE) was carried out to predict in vivo baicalein-AZT interaction. RESULTS Competitive inhibition of baicalein towards AZT metabolism was demonstrated, and the Ki value was calculated to be 101.2 µM. The value of AUCi/AUC was calculated to be 2. CONCLUSION Potential baicalein-AZT interaction was indicated in the present study, indicating the need for monitoring when AZT is co-administrated with baicalein or baicalein-containing herbs.
