Synthesis of Novel Methyl 3-(hetero)arylthieno[3,2-b]pyridine-2-carboxylates and Antitumor Activity Evaluation: Studies In Vitro and In Ovo Grafts of Chick Chorioallantoic Membrane (CAM) with a Triple Negative Breast Cancer Cell Line

open access: yesMolecules, 2021
A series of novel functionalized methyl 3-(hetero)arylthieno[3,2-b]pyridine-2-carboxylates 2a–2h were synthesized by C-C Pd-catalyzed Suzuki-Miyaura cross-coupling of methyl 3-bromothieno[3,2-b]pyridine-2-carboxylate with (hetero)aryl pinacol boranes ...

Drug-resistant malaria [PDF]

open access: yesTrends in Parasitology, 2005
In the past 21 years, a modest increase in the range of antimalarial drugs approved for clinical use has been complemented by a more impressive expansion in the analysis and understanding of the molecular mechanisms underlying resistance to these agents.

Drug resistant HIV [PDF]

open access: yesBMJ, 2007
HIV has an impressive ability to replicate, mutate, and diversify, so developing drugs or vaccines that can fully contain the virus is a challenge. The only consistently successful way to prevent replication of HIV is to administer a potent combination regimen that contains at least two and preferably three antiretroviral drugs.

Novel and reported compensatory mutations in rpoABC genes found in drug resistant tuberculosis outbreaks

open access: yesFrontiers in Microbiology
BackgroundRifampicin (RIF) is a key first-line drug used to treat tuberculosis, a primarily pulmonary disease caused by Mycobacterium tuberculosis. RIF resistance is caused by mutations in rpoB, at the cost of slower growth and reduced transcription ...

Drug resistance in malaria [PDF]

open access: yesBritish Medical Bulletin, 1998
Drug resistance in malaria is now widespread and in many parts of the world is making treatment increasingly difficult. This article reviews current knowledge of the mechanisms and extent of resistance of Plasmodium falciparum and P. vivax to the available antimalarial drugs, and the recommendations for treating malaria in regions where resistance is ...

MicroRNA and drug resistance [PDF]

open access: yesCancer Gene Therapy, 2010
Chemotherapy is the preferred treatment for malignancies. However, a successful long-term use of chemotherapy is often prevented by the development of drug resistance. Many mechanisms such as gene mutation, DNA methylation and histone modification have important roles in the resistance of cancer cells to chemotherapeutic agents.

Elucidation of critical chemical moieties of metallo-β-lactamase inhibitors and prioritisation of target metallo-β-lactamases

open access: yesJournal of Enzyme Inhibition and Medicinal Chemistry
The urgent demand for effective countermeasures against metallo-β-lactamases (MBLs) necessitates development of novel metallo-β-lactamase inhibitors (MBLIs).

Relapse Versus Reinfection of Recurrent Tuberculosis Patients in a National Tuberculosis Specialized Hospital in Beijing, China

open access: yesFrontiers in Microbiology, 2018
Tuberculosis (TB) recurrence can result from either relapse of an original infection or exogenous reinfection with a new strain of Mycobacterium tuberculosis (MTB).

Using machine learning and big data to explore the drug resistance landscape in HIV.

open access: yesPLoS Computational Biology, 2021
Drug resistance mutations (DRMs) appear in HIV under treatment pressure. DRMs are commonly transmitted to naive patients. The standard approach to reveal new DRMs is to test for significant frequency differences of mutations between treated and naive ...

HIV drug resistance: problems and perspectives [PDF]

open access: yesarXiv, 2012
Access to combination antiretroviral treatment (ART) has improved greatly over recent years. At the end of 2011, more than eight million HIV infected people were receiving antiretroviral therapy in low-income and middle-income countries. ART generally works well in keeping the virus suppressed and the patient healthy.
