Enabling synthesis technologies such as flow chemistry are becoming commonplace in modern laboratories. As more groups start to use this technology, there is an increasing demand to expand the capabilities of laboratory apparatus, in particular for the seamless integration of different types of apparatus from different manufacturers so that they can be used simultaneously and synergistically. Although manufacturers generally provide appropriate control software for use with their particular device ecosystem, these frequently have a limited scope and do not always integrate well with other equipment. For commercial reasons, the control software is rarely provided in a format that can be readily extended by the user to implement control of additional hardware.
Here we describe the use of a new open-source software package and a Raspberry Pi(®) computer for the simultaneous control of multiple flow chemistry devices and its application to a machine-assisted, multi-step flow preparation of pyrazine-2-carboxamide - a component of Rifater(®), used in the treatment of tuberculosis - and its reduced derivative piperazine-2-carboxamide.

Researchers have now synthesized sufficient quantities of E7130, a drug candidate from the halichondrin class, to enable for the first time rigorous studies of its biological activity, pharmacological properties, and efficacy.
Synthetic biologists look to re-engineer cells to make complex molecules for specific needs, including pharmaceuticals. But the trial-and-error process is difficult and time-consuming. Now, by combining two state-of-the-art research approaches, researchers have created a fast, efficient way to engineer and analyze metabolic pathways.
Researchers report that they have developed a faster, easier and cheaper method for making new polypeptides than was previously available. These polypeptides, are the building blocks needed in drug development and the creation of new biomaterials.
