Summary: The study reveals that the new suite of organometallic complexes shows potential as selective drug candidates, but their behavior towards glutathione and trypanothione is not fully understood. At a clinically relevant pH range of 4-5, both complexes undergo rapid reduction in the presence of trypanothione or glutathione with no discernible difference. However, at a higher pH range of 6-7, they behave quite differently towards glutathione.

Summary: Chagas Disease, African sleeping sickness, and leishmaniasis are neglected diseases caused by pathogenic trypanosomatid parasites, which have significant impact in poor countries. Current treatment drugs are toxic, difficult to access, and may lead to drug resistance. Inhibiting essential parasite metabolic pathways unique from the host can lead to more efficient and safe drug development.

Summary: This study found that green tea had a pharmacokinetic interaction with raloxifene that was opposite to the predicted effect. The results suggested that one or more processes involved in intestinal absorption were affected. MRP3 was the only identified transporter that may contribute to the interaction. There was no evidence that green tea interrupted raloxifene enterohepatic recycling through inhibition of bacterial beta-glucuronidase activity. The existing gut microbiota may interact with green tea to influence raloxifene stool recovery.

Summary: The life cycle of a drug starts from its discovery and ends when it is disposed. Various entities such as drug discovery companies, manufacturers, regulatory agencies, suppliers, pharmacies, patients, and healthcare providers are involved in this process. Transparency, traceability, automation, and data security play crucial roles in ensuring effective and safe transactions among all parties. However, challenges like scalability, energy consumption, regulations, standards, and complexity hinder the adoption of new technology that can fulfill these requirements. This article highlights how blockchain technology can track, accelerate, and enhance the efficiency of complex operations like pharmaceutical development.

Summary: To improve the drug-like properties of HG-9-91-01, a series of pyrimidine-5-carboxamide derivatives were designed and synthesized through a molecular hybridization strategy. The most promising compound 8h showed good activity and selectivity on SIK1/2, excellent metabolic stability, increased in vivo exposure, and suitable plasma protein binding rate. This research indicates that compound 8h has the potential to be developed as an anti-inflammatory drug candidate.

Summary: ADP-ribosyltransferases use NAD(+) to catalyze substrate ADP-ribosylation and regulate cellular pathways or contribute to bacterial pathogenicity. Recent studies have suggested nucleic acids as targets of reversible ADP-ribosylation. This research provides evidence of specific ADP-ribosylation of DNA in cells through the DarT-DarG system in bacteria, including global pathogens. The study reveals the structure and mechanism of the DarT enzyme, showing its evolution into specific DNA-modifying enzymes and its role in regulating growth through DNA ADP-ribosylation.

Summary: 5-nitro-furan nitrones (1) and 5-nitro-thiophene nitrones (2) were synthesized in one step and showed potent leishmanicidal activity, particularly against intracellular amastigote forms of Leishmania amazonensis and L. infantum. The redox potential of the compounds was modulated by the nitrone group, which could potentially slow the development of resistance. Oral administration of 1b in mice infected by L. infantum significantly reduced parasite load in the spleen and liver.

Summary: ADP-ribosylation signalling plays a crucial role in the DNA damage response of mammals, and its mechanism in fruit flies has been established using a multidisciplinary approach. Ser-ADPr is the major form of ADP-ribosylation in the DNA damage response of Drosophila melanogaster, and its formation depends on the dParp1:dHpf1 complex. The findings suggest that fruit flies are valuable model organisms to study the physiological role of Ser-ADPr signalling.

Summary: This study identifies ERCC6L2 as a key regulator of centromere inheritance and replication, as well as replication of genomic repeats and non-canonical DNA structures. ERCC6L2 interacts with the DNA-clamp PCNA and restricts DNA end resection. The findings provide a mechanistic model for the diverse functions of ERCC6L2 in DNA repair and replication, and offer molecular insights into its role in human diseases.

Summary: A benzothiophene compound with activity against Leishmania donovani was found, with oxidosqualene cyclase (OSC) identified as its target. The amplification of the OSC gene was associated with resistance to the compound, and introduction of an ectopic copy of the gene reduced susceptibility. Biochemical analyses showed substrate accumulation and product depletion in cells treated with the compound, confirming direct binding of the compound to OSC.
