Converting Woodchips Into Pharmaceutical Ingredients
Production of hazardous waste during drug manufacturing is a serious concern for the pharmaceutical industry. Typically, large amounts of flammable solvents are used during these processes, which usually require several steps to make structurally complex drugs. Researchers now report in the journal ACS Central Science a method to produce pharmaceutically relevant compounds in just two or three steps, with water as the only waste product, using renewable woodchips as starting material. The process takes advantage of the lignin component of wood. Lignin consists of cross-linked phenolic compounds that give wood its strength. During paper production, it is removed from wood to prevent the resulting paper from yellowing, and, counterintuitively, to increase the strength of the paper. This process generates a huge amount of unwanted lignin, so researchers have been studying ways to repurpose the material for many years. While several groups recently developed strategies for depolymerizing lignin, the big question remained: What kind of useful products could be obtained from it? Katalin Barta and colleagues realized that, coincidentally, lignin derivatives share many complex structural features with modern pharmaceuticals, making them ideal starting materials to synthesize potential drug candidates. By exploiting this natural bounty, they could skip the typically laborious and waste-generating steps traditionally needed to create these drugs from petrochemicals.

Nanoform Releases Next-Generation AI-based Drug selection Tool

Nanoform | March 23, 2021

Nanoform innovative nanoparticle medicine enabling company next generation of its STARMAP® AI artificial intelligence platform nanoparticle bioavailability excipient microns nm CESS technology silico pharma drugs lifecycle managementNanoform, an innovative nanoparticle medicine enabling company, has today dispatched the next generation of its STARMAP® AI (artificial intelligence) platform, v2.0. The technology uses scanty information AI to expand trial results from its CESS® nanoparticle designing process with detailed master information, permitting dependable expectations to be made in regards to accomplices' likely success of nanoforming their medication atoms. CESS® is a nanoparticle platform technology which produces unadulterated homogeneous medication particles from arrangement in a without excipient process. By diminishing the molecule size e.g., from 10 microns to 50 nm, the particular surface territory can be expanded by as much as 1000-crease, subsequently improving disintegration rate, solvency, and bioavailability. Subsequently, Nanoform can help pharma accomplices progress atoms into advancement that in any case might not have been conceivable. It additionally opens up energizing opportunities for a wide scope of novel medication conveyance applications. STARMAP® is a computerized form of the CESS® technology that empowers in silico tries in enormous amounts, making quick forecasts of which atoms ought to be nanoformed. This is significant since there are more potential medication atoms than particles in the known universe. STARMAP® can be a useful asset for pharma accomplices to pick appropriate medication contender for additional improvement from their huge libraries. The benefits may incorporate quicker way to advertise and additional opportunities for widening and extending drug pipelines while at the same time expanding the likelihood of medication improvement success. The STARMAP® platform can have wide materialness in drug disclosure and advancement just as in lifecycle management for existing promoted drugs and 505b2-like item improvement methodologies. "AI algorithms developed for big data have so far struggled to live up to expectations in pharma because the data, especially for early assets (drug discovery, drug screening), that is available to pharma is typically insufficient for generating reliable predictions. We believe sparse-data AI will work much better - in practice, this means augmenting experimental results with detailed expert knowledge, which can be used to prevent the AI from predicting outcomes that are nonsensical based on prior understanding. There is a lot of untapped potential in sparse-data AI for the pharma industry and the field continues to undergo rapid development in both academia and the industry in general," said Prof. Jukka Corander, Head of AI at Nanoform. "By determining which drug candidates are ideal for our CESS® process, the next-gen STARMAP® platform can potentially create new opportunities for our pharma partners. These can include both revisiting drug candidates unnecessarily discarded by AIs trained on old particle engineering techniques, and rapidly picking winners among new drug candidates. Ultimately, the benefit of more advanced AI will be felt by patients as new therapies are accelerated to market," commented Christian Jones, Chief Commercial Officer at Nanoform

Innovation Zed Announce 2022 Launch of InsulCheck DOSE Add-on Technology for Insulin Pens

Zed | November 15, 2021

Innovation Zed, developer of novel diabetes management technologies headquartered at NovaUCD, at University College Dublin, Ireland are delighted to announce today the arrival of the much anticipated InsulCheck DOSE technology that will be coming to market in 2022. "It is with great excitement that we announce the arrival of our InsulCheck DOSE by Innovation Zed. As the third generation product of the InsulCheck family, this technology has been a dream of our company from its very inception and this product is the culmination of over a decade of work to support multiple daily injection (MDI) pen users. We understood the difficult challenges presented by various injection pens and in particular the difficulties in working on a technology to reliably and accurately support low-cost disposable pens. This is the reason we at Innovation Zed took an incremental approach to developing the InsulCheck DOSE product.We have taken a unique approach in developing this technology by working closely with users, caregivers, software developers, medical device specialists and previous generations of InsulCheck products to design and develop a product that bolsters and supports the needs of all stakeholders.'' Dr Dean Minnock, CEO at Innovation Zed Innovation Zed has collaborated with SHL Medical in the development of InsulCheck DOSE. SHL Medical is a world-leading provider of drug delivery solutions and also offers design-to-build and contract manufacturing services for various medical products through its subsidiary, SHL Technologies. What is InsulCheck DOSE? InsulCheck DOSE is a single unit add-on device for pen injectors that automatically captures dose value dialled, injection event time stamp, temperature and mounting/unmounting events. Through Bluetooth® Low Energy (BLE) technology, InsulCheck DOSE transmits these data points to a paired companion software platform in real time for inclusion in diabetes management therapy. "InsulCheck DOSE technology supports MDI users by enhancing their traditional injection pen and transforming it into a smart pen that can optimise their treatment and reduce the stresses caused by MDI therapy. Through this technology we are enabling every MDI user to make their existing injection pen a smart pen without having to compromise or change from their existing HMO or health service provider" - said Dr Minnock. InsulCheck DOSE Features The technology utilises a multi-sensor approach to accurately detect and register the actual dosage dialled and provide an injection event time stamp to log the event. The incorporated temperature sensors constantly monitor the ambient temperature of the area surrounding the injection pen, providing safety notifications to the user if the surrounding temperature may affect the drug housed inside the pen. Using an OLED display, InsulCheck DOSE provides visual information and feedback to the user, helping improve best practice procedures. A rechargeable lithium battery powers the DOSE device and is capable of operating well over 1 week at a time between charges. As a BLE enabled product, all data captured by InsulCheck DOSE is transferred in real time to a paired mobile application. If the user does not wish or is unable to remain connected with a companion software platform, InsulCheck DOSE has built-in memory to store over 40 days' worth of injection history at a time. Through modification of the sleeve component and firmware refinement, InsulCheck DOSE can become applicable to all injection pens for various drug treatments. At launch, it will support a range of reusable and disposable injection pens on the insulin market from Novo Nordisk, Lilly and Sanofi. "Our ability to learn, adapt and improve our technology is one of the key aspects of InsulCheck DOSE and one that separates us greatly from our competitors. The future-proof design of InsulCheck DOSE means that it can be adapted to support the various pen mechanisms in use today, whilst maintaining accuracy and reliability for the patient. Among the numerous unique features of this product is the built in Firmware Over The Air (FOTA) capability which allows continuous optimisation of the device's firmware even when deployed in the field. That future-proofing allows InsulCheck DOSE to adapt to physical injection pen variations from the pen manufacturers and improve on device performance 'on the go' from real world user behaviours" - said Dr Minnock. Value Proposition The InsulCheck DOSE device helps patients, automatically track their daily injection and monitor treatment adherence. The intended use of InsulCheck DOSE is as a supporting component in a management ecosystem for therapy optimisation, remote monitoring and enhanced connected care. Dr Minnock explained, "InsulCheck DOSE is a disruptive technology that will revolutionise an entire market and change the lives of millions of MDI users worldwide.
