Behavioural activation for people in custody with depression: A protocol for a feasibility randomised controlled study.

People in custody are at high risk of developing depression. Accessing psychological treatments in a prison setting is a particular challenge, in part, due to difficulties accessing specialist mental health workers. Behavioural Activation (BA) may be helpful in improving health outcomes for people in custody experiencing depressive symptoms.

Bayesian Self-Optimization for Telescoped Continuous Flow Synthesis.

The optimization of multistep chemical syntheses is critical for the rapid development of new pharmaceuticals. However, concatenating individually optimized reactions can lead to inefficient multistep syntheses, owing to chemical interdependencies between the steps. Herein, we develop an automated continuous flow platform for the simultaneous optimization of telescoped reactions.

Continuous Flow Chiral Amine Racemization Applied to Continuously Recirculating Dynamic Diastereomeric Crystallizations.

A new, dynamic diastereomeric crystallization method has been developed, in which the mother liquors are continuously separated, racemized over a fixed-bed catalyst, and recirculated to the crystallizer in a resolution-racemization-recycle (R) process. Separating the racemization from crystallization overcomes problems of using catalysts , that suffer conflicting sets of conditions, inhibition, and separation. Continuous racemization has been achieved through the covalent attachment of [IrCp*I] SCRAM catalyst to Wang resin solid support to give a fixed-bed catalyst.

Cediranib Maleate-From Crystal Structure Toward Materials Control.

Cediranib maleate is an active pharmaceutical ingredient (API) in phase III of development within AstraZeneca's oncology portfolio. Analysis of the crystal structure of this API confirmed that the selected salt form was robust. The salt formation step had to be redesigned to avoid an unwanted metastable polymorph.

Stereoretentive Etherification of an α-Aryl-β-amino Alcohol Using a Selective Aziridinium Ring Opening for the Synthesis of AZD7594.

A selective aziridinium ring-opening was used to etherify an α-aryl-β-amino alcohol with stereochemical retention. This transformation was achieved in a biphasic system to address phenoxide solubility and the formation of a sulfonate ester impurity. The protecting group strategy was directed by a stability study of the activated α-aryl-β-amino alcohol in this system.

Shelf lives of aseptically prepared medicines--stability of piperacillin/tazobactam in PVC and non-PVC bags.

Parenteral aseptic preparations of piperacillin/tazobactam are used frequently in hospitals, but there is limited published information on their stability in polyvinyl chloride (PVC) and polyolefine laminate (non-PVC). The purpose of this study was to evaluate the stability in these containers and to determine the optimum validated shelf life so that the formulations may be prepared in bulk in appropriately licensed facilities. In the first study, the stability of piperacillin/tazobactam 45 mg/ml was determined in polyvinyl chloride and polyolefine laminate bags in 0.

Shelf lives of aseptically prepared medicines--stability of hydrocortisone sodium succinate in PVC and non-PVC bags and in polypropylene syringes.

Parenteral aseptic preparations of hydrocortisone sodium succinate (HSS) are used frequently in hospitals, but little definitive stability information is available. The purpose of this study was to obtain ultimate shelf lives for typical formulations so that they may be prepared in bulk in appropriately licensed facilities. In the first study, the stability of HSS, 1mg/ml, was determined in polyvinyl chloride (PVC) bags and polyolefine (non-PVC) bags, in 0.

Shelf lives of aseptically prepared medicines--stability of netilmicin injection in polypropylene syringes.

There is no published information on the stability of netilmicin solutions in prefilled syringes. The purpose of this study was to evaluate the stability of netilmicin in polypropylene syringes and to determine the optimum validated shelf life so that they may be prepared in bulk in appropriately licensed facilities. The syringes containing netilmicin 10 or 100mg/ml were stored at 7 degrees C, room temperature in the light (RTL) and 25 degrees C/60% relative humidity for up to 300 days.
