In the title compound, C(14)H(9)ClN(2)O, the quinazoline unit is essentially planar, with a mean deviation from the least-squares plane defined by the ten constituent ring atoms of 0.027 (2) Å. The dihedral angle between the mean plane of the quinazoline ring system and the 4-chloro-phenyl ring is 44.63 (5)°. In the crystal, mol-ecules are linked by inter-molecular C-H⋯N and C-H⋯O hydrogen bonds, forming infinite chains of alternating R(2) (2)(6) dimers and R(2) (2)(14) ring motifs.

Adherence to tuberculosis (TB) treatment in high compared to low TB burden countries: study protocol for a systematic review and meta-analysis with a qualitative meta-synthesis of themes.
BMJ Open

Faculty of Health Sciences, Simon Fraser University, Burnaby, BC, Canada.
Introduction: Non-adherence to tuberculosis (TB) treatment poses a significant challenge to effective TB management globally and is a major contributor to the emergence of multidrug-resistant TB. Although adherence to TB treatment has been widely studied, a comprehensive evaluation of the comparative levels of adherence in high- versus low-TB burden settings remains lacking. The objective of this systematic review and meta-analysis is to assess the levels of adherence to TB treatment in high-TB burden countries compared to low-burden countries.

Dysregulated lipid metabolism is linked to tumor progression. In this study, we identified Niemann-Pick C1-like 1 (NPC1L1) as a downstream effector of PKM2. In breast cancer cells, PKM2 knockout (KO) enhanced NPC1L1 expression while downregulating peroxisome proliferator-activated receptor α (PPARα) signaling pathway.
