Corticosteroids are the standard first-line treatment for primary immune thrombocytopenia (ITP), with a high initial response but unsatisfactory sustained response (SR). Additionally, corticosteroids usually lead to hyperglycaemia especially in patients with pre-existing type 2 diabetes mellitus (T2DM). Besides reducing the blood glucose levels, metformin was found to have immunomodulatory effects.

Chiral coumarins and their derivatives are ubiquitous structural motifs found in an array of biologically and therapeutically active natural products and drugs. Herein, a highly enantioselective dual remote copper-catalyzed vinylogous alkynylallylic substitution of yne-allylic esters with coumarins has been developed. The practicality of this method is exemplified by the use of readily available starting materials; mild reaction conditions; excellent regio-, enantio-, and stereoselectivities; and the very broad substrate scope (67 examples), while the scalability and further applications of this method are illustrated by the gram-scale reaction and the series of derivations of the products.

Tubulointerstitial fibrosis (TIF) is one of the key indicators in evaluating the renal function of patients. Mild TIF can cause a vicious cycle of renal tubular glomerular injury and aggravate renal disease. Therefore, studying the mechanisms underlying TIF is essential to identify therapeutic targets, thereby protecting the renal function of patients with timely intervention.

Article Synopsis
  • A study explored the potential benefits of S-9-PAHSA, a novel fatty acid, on metabolic issues and neuronal protection in mouse models of type 2 diabetes mellitus (T2DM) induced by a high-fat diet.
  • S-9-PAHSA significantly lowered blood glucose levels and increased insulin sensitivity, while also reducing apoptosis and oxidative stress in both mouse brains and cultured neuron-like cells (PC12 cells).
  • The neuroprotective effects of S-9-PAHSA were linked to CAIII, as knocking down CAIII reduced its protective abilities, indicating CAIII plays a crucial role in mediating these effects.

Impressive progress has been made in the copper-catalyzed asymmetric propargylic substitution (APS) reaction, but its use in remote asymmetric yne-allylic substitution remains a challenging topic. Herein, we report the first remote enantioselective copper-catalyzed sulfonylation of yne-allylic esters with sodium sulfinates. The reaction is assumed to occur via a copper-vinylvinylidene species as the key reactive intermediate.

Rickettsioses are caused by a broad range of obligate intracellular bacteria belonging to the genus Rickettsia that can be transmitted to vertebrate hosts through the bite of infected arthropod vectors. To date, emerging or re-emerging epidemic rickettsioses remain a public health risk due to the difficulty in diagnosis, as diagnostic methods are limited and not standardized or universally accessible. Misdiagnosis resulting from a lack of recognition of the signs and symptoms may result in delayed antibiotic treatment and poor health outcomes.

  • Cell senescence is a key mechanism of aging, and while its role in tissues like fat, pancreas, and liver in relation to type 2 diabetes is established, its direct effects on neurons are still unclear.
  • In this study, researchers created a high glucose and palmitic acid (HGP) environment to simulate diabetes in neuronal cells and found that this condition triggered significant senescence-like traits in the neurons, linked to changes in specific proteins and cellular processes.
  • The findings suggest that diabetes can directly lead to neuronal senescence by increasing NRSF/REST levels, which then disrupts the mTOR-autophagy pathway, indicating a potential target for future therapies.

  • The study analyzed 298 Mongolian patients with cerebral infarction to determine age distribution and the relationship between thromboelastography (TEG) and standard coagulation measures.
  • Most patients were aged 61-70, indicating a younger trend in onset age, with significant correlations found between TEG results and certain coagulation parameters.
  • While there is a correlation between TEG and coagulation measurements, the consistency between the two methods is weak, meaning they cannot substitute for one another in clinical practice.

Diabetes is one of the well-established risk factors of stroke and is associated with a poor outcome in patients with stroke. Previous studies have shown that the expression of neuron restrictive silencer factor (NRSF) is elevated in diabetes as well as ischemic stroke. However, the role of NRSF in regulating an outcome of diabetic ischemic stroke has not been completely understood.

All- retinoic acid-based differentiation therapies have succeeded in the treatment of acute promyelocytic leukemia, which is a rare subtype of acute myeloid leukemia (AML). Their clinical efficacy is negligible, however, for other subtypes of AML. Here, we showed that strobilurin derivatives, a well-established class of inhibitors of mitochondrial electron transport chain (ETC) complex III, possessed differentiation-inducing activity in AML cells.

Tomato yellow leaf curl virus (TYLCV), a plant DNA virus of the genus Begomovirus, is transmitted by whiteflies of the Bemisia tabaci species complex in a persistent manner. Our previous study indicated that activation of the apoptosis pathway in whiteflies could facilitate TYLCV accumulation and transmission. Considering that temperature change can influence the spread of insect-borne plant viruses, we focused on plant virus induced-apoptosis to investigate the underlying mechanism of temperature regulation on plant virus transmission via an insect vector.
