1. The Ototoxicity of Chloroquine and Hydroxychloroquine: A Systematic Review
Abstract Introduction Chloroquine and hydroxychloroquine are antimalarial drugs widely used in the treatment of rheumatic diseases. With the global pandemic caused by the new coronavirus, there was an increase in the prescription of these drugs, which led to a major concern regarding their ototoxic effects. Objectives The objective of the present study was

2. Synthesis and SARS-CoV-2 3CL Protease Inhibitory Effects of Oxazolidinone Derivatives
The 3-chymotrypsin-like protease (3CLpro) is an attractive target for the development of anti-SARS (severe acute respiratory syndrome) drugs. In this work, a series of oxazolidinone derivatives 3a-3v were synthesized and their inhibitory activities against SARS coronavirus 2 (SARS-CoV-2) 3CLpro were evaluated by the fluorescence resonance energy transfer (FR

3. Synthesis and Anti-Chikungunya Virus (CHIKV) Activity of Novel 1,4-Naphthoquinone Sulfonamide and Sulfonate Ester Derivatives
Chikungunya virus (CHIKV) is a re-emerging disease caused by an alphavirus of the Togaviridae family. Since its first description in 1952, the disease has spread worldwide, affecting populations in both tropical and temperate countries. To date, there is no licensed vaccine or specific pharmacological treatment. Therefore, there is an increasing urgency in d

4. METHODS FOR EXTRACTION AND ISOLATION OF AGATHISFLAVONE FROM POINCIANELLA PYRAMIDALIS
Agathisflavone is a natural biflavone with restricted occurrence in plants. This biflavone presents several biological activities and can be important to developing new drugs. Obtaining such a molecule on a large scale for in vivo tests is a challenge. To date, there are no reports regarding its synthesis; thus, it is important to improve and develop methods

5. Molecular Modeling and Chemical Synthesis of New Safrol Oxime Ether Derivatives
Leishmaniasis, a neglected tropical disease with a high worldwide incidence, is considered a public health issue in Minas Gerais and Brazil, with a high degree of morbidity, not to mention the lack of therapeutic arsenal. The cysteine protease (rCPB2.8) and cyclin dependent kinase (CRK3), important enzymes for the parasite’s feasibility, were the targets c

6. Bioconjugation Between CdTe Quantum Dots and a Cationic Protein: An Analytical Method to Determine Protamine in Drug and Urine Samples
CdTe quantum dots (QD-CdTe) functionalized with mercaptosuccinic acid (MSA) were synthesized in an aqueous medium, varying synthesis time from 0.5 to 4 h. The nanoprobe were characterized by a direct relationship between synthesis time and QD size (2.61-3.04 nm). The QD-CdTe-MSA interacted with protamine (PT), a cationic protein, forming a bioconjugate, thus

7. Design, Synthesis and Antifungal Activity of New Schiff Bases Bearing 2-Aminothiophene Derivatives Obtained by Molecular Simplification
Seventeen Schiff bases bearing 2-aminothiophene derivatives were designed and synthesized using molecular simplification. The resulting compounds (4a-4q) were evaluated for their in vitro antifungal activity against dermatophytes. Prediction of their druglikeness and pharmacokinetic properties, establishment of their structure-activity relationships (SAR), a

12. Synthesis and Evaluation of Fenofibric Acid Ester Derivatives: Studies of Different Formulation with Their Bioavailability and Absorption Conditions
A series of fenofibric acid ester pro-drugs (JF-1-7) were synthesized. The pharmacokinetic properties of these pro-drugs were examined after oral administration to rats at a dose of 20 mg kg-1 to evaluate the relative bioavailability in rats. The bioavailability of the ester compounds, JF-1, 2, 3, 4, 5, 6, and 7, was significantly higher than that of fenofib
