Background: Human genetic variants can affect TB and HIV drug metabolism, which may lead to toxicity or treatment failure. We evaluated associations between genetic variants of antiretroviral therapy (ART) and HIV-1 outcomes among TB/HIV patients.
Methods: We included RePORT-Brazil participants with TB/HIV who initiated standard TB treatment [2 months of isoniazid/rifampicin (or rifabutin)/pyrazinamide/ethambutol, then 4 months or more of isoniazid/rifampicin (or rifabutin)], and ART.

Castrate-resistant prostate cancer (CRPC) is one of the most difficult cancers in men and is characterized by a poor prognosis and a high risk of metastasis. The overexpression of the disruptor of telomeric silencing 1-like (DOT1L), which is a specific methyltransferase for histone H3 at lysine residue 79 (H3K79), has been related to poor outcomes in patients with CRPC. Therefore, targeting DOT1L is considered a potential therapeutic approach to overcome the significant medical challenges of CRPC.

Breast cancer is the most common cancer in women worldwide. Many breast cancers originate from the cells lining the milk duct and some become invasive. Breast cancer lacking estrogen, progesterone receptors (ER-, PR-) and epidermal growth factor receptor 2 (HER2-) amplification, termed "Triple negative" (TNBC) is reported to frequently affect Black women and younger women.

The COVID-19 pandemic, exacerbated by persistent viral mutations, underscored the urgent need for diverse inhibitors targeting multiple viral proteins. In this study, we utilized covalent DNA-encoded libraries to discover innovative triazine-based covalent inhibitors for the 3-chymotrypsin-like protease (3CL, Nsp5) and the papain-like protease (PL) domains of Nsp3, as well as novel non-nucleoside covalent inhibitors for the nonstructural protein 12 (Nsp12, RdRp). Optimization through molecular docking and medicinal chemistry led to the development of , a nonpeptide 3CL inhibitor with an IC of 0.

As an important part of anti-AIDS therapy, HIV-1 non-nucleoside reverse transcriptase inhibitors are plagued by resistance and toxicity issues. Taking our reported XJ-18b1 as lead compound, we designed a series of novel diarypyrimidine derivatives by employing a scaffold hopping strategy to discover potent NNRTIs with improved anti-resistance properties and drug-like profiles. The most active compound 3k exhibited prominent inhibitory activity against wild-type HIV-1 (EC = 0.
