In the title compound, C(21)H(17)FN(4)O(2)S, the planar indole fused-ring [maximum deviation 0.009 (1) Å] makes dihedral angles of 54.75 (9) and 14.90 (9)°, respectively, with the phenyl ring and the dihydro-thia-zolyl ring. The -CH2CH=CH(2) substituent is disordered over two positions in a 0.51 (1):0.49 (1) ratio. An intra-molecular N-H⋯S hydrogen bond generates an S(5) ring motif. The two independent mol-ecules are linked into a dimer by two N-H⋯O hydrogen bonds, forming an R(2) (2)(10) ring motif. The crystal structure features inter-molecular C-H⋯π and π-π stacking [centroid-centroid distance = 3.679 (1) Å] inter-actions. C-H⋯O and C-H⋯F inter-actions are also present.

Structural basis for assembly and function of the Salmonella flagellar MS-ring with three different symmetries.
Commun Biol

The flagellar MS-ring is the initial template for flagellar assembly and houses the flagellar protein export complex. The MS-ring has three parts of different symmetries within the ring structure by assembly of FliF subunits in two different conformations with distinct arrangements of three ring-building motifs, RBM1, RBM2, and RBM3. However, it remains unknown how these symmetries are generated.

Diabetes mellitus, particularly type 2 diabetes, is a growing global health challenge characterized by chronic hyperglycemia due to insulin resistance. One therapeutic approach to managing this condition is the inhibition of α-glucosidase, an enzyme involved in carbohydrate digestion, to reduce postprandial blood glucose levels. In this study, a series of thiosemicarbazide-linked quinoline-piperazine derivatives were synthesized and evaluated for their α-glucosidase inhibitory activity, to identify new agents for type 2 diabetes management.

ORF2p (open reading frame 2 protein) is a multifunctional multidomain enzyme that demonstrates both reverse transcriptase and endonuclease activities and is associated with the pathophysiology of cancer. The 3D structure of the entire seven-domain ORF2p complex was revealed with the recent achievements in structural studies. The different arrangements of the CTD (carboxy-terminal domain) and tower domains were identified as the "closed-ring" and "open-ring" conformations, which differed by the hairpin position of the tower domain, but the structural diversity of these complexes has the potential to be more extensive.

Fatty acids (FAs) are essential building blocks for all the domains of life, of which bacterial de novo synthesis, called type II FA synthesis (FAS II), is energetically expensive. The recycling of exogenous FAs (eFAs) partially relieves the FAS II demand and, therefore, compromises the efficacy of FAS II-directed antimicrobials. The versatile acyl-acyl carrier protein (ACP) synthetase, AasS, enables bacterial channeling of diverse eFA nutrients through holo-ACP, an activated form of ACP.

Introduction: Cancer cachexia (CC) is characterized by weight loss with specifically reduced skeletal muscles and adipose tissues in patients with late-stage cancer. Dihydroartemisinin (DHA), an effective antimalarial derivative of artemisinin, has been demonstrated to have anti-inflammatory and antitumor properties.
Materials And Methods: This study examined the effects of DHA on the Lewis lung carcinoma (LLC)-induced CC mouse model.
