A new SO2 surrogate is reported that is cheap, bench-stable, and can be accessed in just two steps from bulk chemicals. Essentially complete SO2 release is achieved in 5 minutes. Eight established sulfonylation reactions proceeded smoothly by ex situ formation of SO2 by utilizing a two-chamber system in combination with the SO2 surrogate. Furthermore, we report the first direct aminosulfonylation between aryl iodides and amines. Broad functional group tolerance is demonstrated, and the method is applicable to pharmaceutically relevant substrates, including heterocyclic substrates.

To develop a quantitative systems pharmacology model to describe the effect of dapagliflozin (a sodium-glucose co-transporter-2 [SGLT2] inhibitor) on glucose-insulin dynamics in type 2 diabetes mellitus (T2DM) patients, and to identify key determinants of treatment-mediated glycated haemoglobin (HbA1c) reduction.

Glycaemic control during dapagliflozin treatment was mechanistically characterized by integrating components representing dapagliflozin pharmacokinetics (PK), glucose-insulin homeostasis, renal glucose reabsorption, and HbA1c formation. The model was developed using PK variables, glucose, plasma insulin, and urinary glucose excretion (UGE) from a phase IIa dapagliflozin trial in patients with T2DM (NCT00162305). The model was used to predict dapagliflozin-induced HbA1c reduction; model predictions were compared to actual data from phase III trials (NCT00528879, NCT00683878, NCT00680745 and NCT00673231).

The integrated glucose-insulin-dapagliflozin model successfully described plasma glucose and insulin levels, as well as UGE in response to oral glucose tolerance tests and meal intake. HbA1c reduction was also well predicted. The results show that dapagliflozin-mediated glycaemic control is anticorrelated to steady-state insulin concentration and insulin sensitivity.

The developed model framework is the first to integrate SGLT2 inhibitor mechanism of action with both short-term glucose-insulin dynamics and long-term glucose control (HbA1c). The results suggest that dapagliflozin treatment is beneficial in patients with inadequate glycaemic control from insulin alone and this benefit increases as insulin control diminishes.

However, there are still difficult-to-treat cases in which even dose-escalation fails to provide a clinical response. In such cases, combining secukinumab with a conventional systemic agent may be a rational approach. Although methotrexate is most commonly preferred, acitretin may also be considered a good alternative, with its lower hepatotoxic potential. Data are limited regarding the use of combination therapy of secukinumab and acitretin for psoriasis. We herein present three patients with chronic plaque, generalized pustular and erythrodermic psoriasis, respectively, accompanied by multiple comorbidities, in whom skin clearance could not be achieved with several conventional and biologic therapies (including escalated dose regimens of secukinumab in two patients). Tertiapin-Q in vitro Alternatively, we used a combination of secukinumab with low-dose acitretin, which resulted in a complete or almost complete skin clearance in all patients, with no adverse events or increased toxicity. Based on our real-life clinical experience with those patients, acitretin seems an effective and safe option to be used in combination with secukinumab. Even in patients who are refractory to multiple drugs including escalated doses of secukinumab, the addition of low-dose acitretin may be helpful in achieving treatment goals, decreasing the need for switching to another biologic therapy.Pore-forming toxins (PFTs) are important weapons of multiple bacterial pathogens to establish their infections. PFTs generally form pores in the plasma membrane of target cells; however, the intracellular pathogenic processes triggered after pore-formation remain poorly understood. Using Caenorhabditis elegans as a model and Bacillus thuringiensis nematicidal Cry PFTs, we show here that the localized PFT attack causes a systemic mitochondrial damage, important for the PFT toxicity. We find that PFTs punch pores only in gut cells of nematodes, but unexpectedly mitochondrial disruption is able to occur in distal unperforated regions, such as the head and muscle tissues. We demonstrate that PFTs affect the activity of the mitochondrial respiratory chain (MRC) complex I resulting in the loss of mitochondrial membrane potential (ΔΨm ), which causes further mitochondrial fragmentation and the reduction of total mitochondrial content. Worms with decreased ΔΨm or inhibited MRC activity show higher sensitivity to PFTs. The inhibition of mitochondrial fission or the increase of mitochondrial content markedly improves the survival of animals treated with PFTs. These findings suggest that mitochondrial changes underpin PFT-mediated toxicity against nematodes and that systemic mitochondrial disruption caused by localized pore-formation represents a conserved key intracellular event in the mode of action of PFTs.

Self-compassion can facilitate self-improvement motivation. We examined the effects of self-compassion in response to dietary lapses on outcomes relevant to weight-loss strivings using a longitudinal design. The indirect effects of self-compassion via guilt and shame were also explored.

An Ecological Momentary Assessment methodology was employed with a sample of adults who were overweight or obese attempting to lose weight via dietary restriction (N=56; M

=34.88; SD=13.93; M

=32.50; SD=6.88) and who responded to brief surveys sent to their mobile phones twice daily for two weeks.

Dietary temptations and lapses were assessed at each diary entry, and self-compassion in response to dietary lapses, intention to continue dieting, weight-loss-related self-efficacy, negative reactions to the lapse, and self-conscious emotions were surveyed on occasions when participants reported having experienced a dietary lapse. The participants were also weighed in a laboratory prior to the EMA phase and via self-report straight after the EMA phase.
