Ketoconazole

Ketoconazole is a synthetic imidazole antifungal agent used to treat a wide range of fungal infections, including candidiasis, blastomycosis, coccidioidomycosis, and histoplasmosis.
It works by inhibiting the fungal enzyme lanosterol 14-alpha-demethylase, which is essential for the production of ergosterol, a key component of the fungal cell membrane.
Ketoconazole is available in topical, oral, and intravenous formulations, and is commonly prescribed for both systemic and localized fungal infections.
Reserchers can utilize PubCompare.ai, an AI-driven platform, to optimize Ketoconazole research by locating relevant protocols from literature, preprits, and patents, and leveraging AI-driven comparisons to identify the best protocolls and products for their projects.
This can help improve reproducibility and accuaracy in Ketoconazole-related studies.

For the antifungal bioassays, two strains of Aspergillus fumigatus were used: Aspergillus fumigatus (ATCC 204305), and Aspergillus fumigatus (human clinical isolate). The organisms are deposited at the Mycological Laboratory, Department of Plant Physiology, Institute for Biological Research “Siniša Stankovic,” Belgrade, Serbia.
The micromycetes were maintained on malt agar and the cultures were stored at 4°C and sub-cultured once a month. The antifungal assay was carried out by a modified microdilution technique [45 (link),46 (link)] in order to determine the minimum inhibitory (MIC) and minimum fungicidal concentrations (MFC) of the examined compounds. Briefly, the fungal spores were washed from the surface of agar plates with sterile 0.85% saline containing 0.1% Tween 80 (v/v). The spore suspension was adjusted with sterile saline to a concentration of approximately 1.0×105 in a final volume of 100 μL per well. The examined compounds were dissolved in 5% of DMSO, serially diluted in broth malt medium after which fungal inoculum was added. The microplates were incubated for 72 h at 28°C. The lowest concentrations without visible growth (in a binocular microscope) were defined as MICs. The fungicidal concentrations (MFCs) were determined by serial sub cultivation of 2 μL of the wells content into microtiter plates containing 100 μL of broth per well and further incubation for 72 h at 28°C. The lowest concentration with no visible growth was defined as MFC indicating 99.5% killing of the original inoculum. The commercial antifungals econazole and ketoconazole were used as positive controls.

Candida parapsilosis strains (Table S1) were grown in YPD medium (1% yeast extract, 2% peptone, 2% glucose) at 30°C. For colony selection 2% agar was added. To select for transformants, nourseothricin (Werner Bioagents Jena, Germany) was added to YPD agar at a final concentration of 200 µg ml−1. Transformants containing the LEU2 and HIS1 markers were selected on synthetic complete (SC; 0.19% yeast nitrogen base without amino acids and ammonium sulphate, 0.5% ammonium sulphate, 2% dextrose, 0.075% mixture of amino acids, 2% agar) media without leucine or histidine. For biofilm formation, C. parapsilosis was grown in synthetic defined (SD) medium (0.67% yeast nitrogen base) containing 50 mM glucose. C. albicans was grown in Spider media (1% nutrient broth, 1% mannitol, 0.2% potassium phosphate). The media used for phenotype screening is shown in Table S2. All deletion strains were grown in 96 well plates in YPD media at 30°C overnight. The cultures were then diluted 1∶100 into a new 96 well plate containing fresh YPD media. The strains were then pinned onto agar plates using a 48 pin bolt replicator. Plates were incubated at 30°C and photographed after 2 and 3 days of growth. Each knockout was scored on growth in comparison to the control strains (CLIB214 and CPRI) on the same media, where −4 indicates a severe growth defect, −3, −2, and −1 indicate strong, moderate and marginal growth defects, 0 is similar to the control strains, and +1 is stronger growth than control strains. Scores were assigned only where the two independent replicates had the same behavior. Screens were repeated at least twice. Growth on different chemical concentrations (e.g. CuCl2, ketoconazole) were combined to give a single score (see Table S2). Deletion strains with interesting phenotypes were further validated by plating exact numbers of cells in decreasing concentration on test media. Control strains were included in each plate. Scores were converted to a Heatmap using Bioconductor [114] (link).

Neurocortical spheroids were generated from human pluripotent stem cells as previously described with variations noted below3 (link).
To pattern neurocortical spheroids, pluripotent stem cell colonies cultured on vitronectin (Gibco #A14700) were lifted using dispase (Gibco #17105–041) at 37°C for 10 minutes. Intact colonies were transferred to individual low-adherence V-bottom 96-well plates (S-Bio Prime #MS-9096VZ) in 200μl Spheroid Starter media with 10μM Rock inhibitor Y-27632 (Calbiochem #688001), 10 μM Dorsopmorphin (Sigma #P5499), and 10 μM SB-431542 (Sigma #S4317). Spheroid Starter media was DMEM/F12 (Invitrogen #11320–033) containing 20% Knock out Serum (Invitrogen #12587–010), Non-essential amino acids (Invitrogen #11140050), Glutamax (Invitrogen #35050061), β-mercaptoethanol and 100U/ml Penicillin/Streptomycin. The same media without rock inhibitor was used for the next five days, after which the media was changed to Neurobasal-A based spheroid media. Neurobasal-A spheroid media was Neurobasal-A medium (Invitrogen #10888022) with added B-27 serum substitute without vitamin A (Invitrogen #12587), Glutamax (Invitrogen #35050061) and 100U/ml Penicillin/Streptomycin. From day 7–25, 20ng/ml FGF-2 (R&D systems #233-FB-25/CF) and 10ng/ml EGF (R&D systems #236-EG-200) were added to the media. Spheroids were cultured in 96-well plates through day 25, with daily half-media changes. On day 25, spheroids were transferred to ultra-low attachment 6-well plates (Corning #CLS3471) at a density of 8–10 spheroids per well and cultured thus through the remainder of the protocol. Also from this point forward 1% Geltrex (Invitrogen # A15696–01) was added to the Neurobasal-A spheroid media. Neural differentiation was induced between days 27 and 41 by supplementing Neurobasal-A spheroid media with 20ng/ml BDNF (R&D systems #248-BD) and 20ng/ml NT-3 (R&D systems #267-N). Half media changes were performed every other day between days 17 and 41.
To generate oligocortical spheroids, beginning on day 50, 10 ng/ml platelet-derived growth factor-AA (PDGF-AA, R&D Systems #221-AA-050) and 10 ng/ml insulin-like growth factor-1 (IGF-1, R&D Systems #291-G1–200) were added to the every-other-day media changes for 10 days. Next, on day 60, 40 ng/ml 3,3’,5-triiodothronine (T3, Sigma #ST2877) was added to the every-other-day media changes for 10 days. When used, small molecules were supplemented during this period. 4μM Ketoconazole and 2 μM Clemastine were added in lieu of T3. GSK2656157 was added in addition to T3.
After day 70, spheroids were matured and maintained in Neurobasal-A spheroid media with every-other-day media changes until completion of the experiment.

The linked information relevant to this study consisted of anonymized identifier codes, ATC codes, dispensing dates, date of entry in the IADB database, sex and age at the time of the first visit at entry to the cohort. The very first interview with the Lifelines Cohort Study participant was considered the baseline measurement and only the data of the baseline measurements (entry period) were used in the comparison of the two databases.
All drugs grouped at a second level of ATC coding were examined in the study. Besides the second level ATC codes, some specific drugs at the chemical level were included in the study. A top list of the several most commonly used drugs in the Netherlands including omeprazole, psylla seeds, macrogol, calcium, hydrochlorothiazide, metoprolol, enalapril, simvastatin, ketoconazole, triamcinolone, clobetasol, levothyroxine, oxazepam, temazepam, paroxetine, fluticasone, mometasone, salbutamol, salmeterol/fluticasone, desloratadine, artificial tears, carbasalate ca., diclofenac and ibuprofen was also examined.
The program SQL Server was used to compare the records of drugs for each participant. The acquired data was then categorized in true positives, true negatives, false positives (FPs) and false negatives (FNs). These values were given in cross-tables, which were used to calculate the concordance. Each of the four cells in these cross-tables were required to have at least 5 participants. If the number of participants was lower than 5 in one or more cells, the drug group or specific drug was disregarded.
In order to address the possible underlying cause of a low agreement, the FNs and FPs were examined. Over-reporting represents the number of FPs. This means that a number of participants reported the use of a certain drug group, while at the same time the prescription was not registered in the pharmacy records. On the other hand, under-reporting represents the number of FNs. This means that the participants did not report the use of a certain drug group, while at the same time the prescription was registered in the pharmacy records. If a drug group or specific drug showed a poor agreement and at the same time a high over-reporting, it could indicate that the database with the self-reported data is better capable in recording the use of this specific drug (or drug group).

Patients were eligible if they had histologically or cytologically confirmed adenocarcinoma of the prostate with documented metastases and had PSA progression, radiographic progression, or both in bone or soft tissue, despite receiving LHRH analogue therapy or undergoing orchiectomy, with a serum testosterone level of 1.73 nmol per liter (50 ng per deciliter) or less. Continued androgen-deprivation therapy was required. Previous antiandrogen therapy and concurrent use of glucocorticoids were permitted but not required. Eligible patients had not received cytotoxic chemotherapy, ketoconazole, or abiraterone acetate, had an Eastern Cooperative Oncology Group performance status grade of 0 or 1 (no symptoms or ambulatory but restricted in strenuous activities), and were either asymptomatic (score of 0 to 1) or mildly symptomatic (score of 2 to 3), as measured on the Brief Pain Inventory Short Form question 3 (on which scores range from 0 to 10, with higher scores indicating a greater severity of pain). Patients with visceral disease, including lung or liver metastases, were eligible, as were patients with New York Heart Association class I or II heart failure. Patients with a history of seizure or a condition that could confer a predisposition to seizure were excluded, although patients taking medications associated with lowering the seizure threshold were eligible.
From September 2010 through September 2012, patients were enrolled at 207 sites globally. All patients were randomly assigned to receive either oral enzalutamide (at a dose of 160 mg) or placebo once daily with or without food. Randomization was stratified according to the study site. Treatment continued until the occurrence of unacceptable side effects or confirmed radiographic progression and the initiation of chemotherapy or an investigational agent. Treatment discontinuation because of an increase in the PSA level alone was discouraged.

The metabolic stability of test compounds was determined as described.57 (link),58 (link) Incubation and experimental conditions with human hepatic microsomal fractions (purchased from BD Gentest as a pooled batch from 6 donors) were as follows: microsomal proteins, 1 mg/mL; bovine serum albumin, 1 mg/mL; substrate, 5 μM; incubation duration, 20 min; cytochrome P-450 monooxygenases (CYPs) and flavin containing monooxygenases (FMOs) cofactor, 1 mM NADPH. Enzyme activity was stopped with 1 volume of acetonitrile. Ketoconazole at a final concentration of 1.5 μM (100-fold above its Ki for CYP3A4) was used for the specific and potent inhibition of enzyme reactions catalyzed by CYP3A4. For each test compound and for each microsomal preparation, three incubations were prepared: absolute reference in buffer (without enzyme material, i.e., microsomes); incubation without NADPH cofactor (with microsomal fractions); and incubation with NADPH (with microsomal fractions). For most compounds, biotransformation, as observed in hepatic microsomal fractions in the presence of the NADPH cofactor, consists of oxidative reactions catalyzed by either CYPs or FMOs. In these conditions, the percentage of total metabolism, which corresponds to oxidative metabolism, was determined as follows: [% total metabolism] ≈ [% oxidative metabolism] = [unchanged compound (UC) peak area − NADPH UC peak area + NADPH] × 100%, where NADPH corresponds to the enzyme cofactor for oxidation reactions catalyzed by either CYP or FMO.
