Synthesis of Blue Emissive Quaternary 9,9-Disubstituted -Methyl-7-azaindole-Appended (Phenylethynyl)-fluorene Derivatives.

A highly functionalized 9,9-disubstituted (phenylethynyl)-fluorene-appended -methyl-7-azaindole derivatives has been synthesized from various fluorene propargylic alcohols and substituted-7-azaindoles using BFOEt as a catalyst. The scope of the reaction was demonstrated by selecting a range of fluorene propargylic alcohols and substituting 7-azaindoles. A plausible reaction mechanism for forming title compounds via propargylic carbocation is postulated.

DMSO-allyl bromide: a mild and efficient reagent for atom economic one-pot -allylation and bromination of 2°-aryl amines, 2-aryl aminoamides, indoles and 7-aza indoles.

A mixture DMSO-allyl bromide has been developed as a reagent for an atom economic one-pot -allylation and aryl bromination under basic conditions. Utilizing this reagent, -allylation-bromination of a number of 2°-aryl amines, aryl aminoamides, indoles, and 7-aza indoles has been achieved. The scope of the substrates and limitations, the synthetic utility of the products, and a plausible reaction mechanism have been proposed.

A time to act: Anti-racist paediatric research.

Research offers the potential for new treatments, programs and services, and underlies decisions about funding that can have profound implications for people's lives. When racism in research is not addressed, children and their families will be unjustly impacted by systemic discrimination, exclusion, and inequity. With a growing acknowledgement that racism is a social determinant of health, and as COVID-19 reveals staggering racial disparities, we believe now is the time for intentional anti-racism initiatives throughout the research ecosystem to prevent further harms in patient care and the lives and futures of children.

Intestinal permeability correlates with behavioural severity in very young children with ASD: A preliminary study.

Systemic inflammation is known to alter behaviour, and since it has been reported that individuals with autism spectrum disorder (ASD) have higher levels of circulating cytokines, it has been hypothesized that systemic inflammation may exacerbate behaviours characteristic of ASD. The acute phase proteins α-2-macroglobulin, C-reactive protein, haptoglobin, serum amyloid P, serum amyloid A, ferritin and tissue plasminogen activator, as well as markers of intestinal permeability (intestinal fatty acid binding protein and lipopolysaccharide) were quantitated in the plasma of very young children with ASD. Behaviour severity was measured using the Autism Diagnostic Interview-Revised (ADI-R), the Autism Diagnostic Observation Schedule (ADOS) and the Vineland Adaptive Behaviour Scale (VABS).
