About

Our mission

AldexChem is a solution and platform provider for the Chemical and Life Science industries. Our mission is to support the development of new therapies that will improve the lives of millions worldwide.

SilBoRed

AldexChem developed a novel hydrosilylation reaction filing its primary IP as SilBoRed™. A technology to reduce esters to aldehydes which are difficult, if not impossible with the standard chemistry toolbox. SilBoRed™ technology opened up a novel chemical space, leading to several industrial applications.

We are dedicated to provide robust and scalable tools for the chemical industries and we develop building blocks for a wide range of applications.

LipexSil

One of these applications is creating novel ionizable cationic lipid families, which belong to the trademark LipexSil™ and filing AldexChem's secondary IP. LipexSil™ lipid families are a solution to one of the most pressing challenges of the pharma industry – the delivery of biologically active agents.

LipexSil™ novel ionizable lipids can be used in the preparation of LNPs to facilitate the therapeutic oligonucleotides into cells.  

Our vision

We strive to solve challenges faced by the pharma industry, such as efficient delivery of biologically active agents with the help of our SilBoRed™ and LipexSil™ technologies. Our vision is to inspire change in the scientific community by pushing the boundaries of chemical synthesis. We think that by empowering the Chemical and Life Science sector with innovative and impactful solutions, we can contribute to a brighter future for all.

Present

2021 September
AldexChem proofs applicability of SilBoRed™ for manufacturing of key components for research and manufacturing
2021 December
First phase synthesis of LipexSil™ 1 st generation lipids is launched.
2022 May
Synthesis and characterisation of the first 100 members of LipexSil™ 1 st generation
lipids are successfully completed.
2022 November
Second phase synthesis of LipexSil™ 1 st generation lipids is initiated.
Reaction scope investigation, and technological development of SilBoRed™ borane
catalysts’ applications are launched.
SilBoRed™ is registered as a Hungarian national trademark (SZTNH), and
applications for international trademarks (WIPO) have been started.
2023 February
Preliminary in vitro biological results prove good performance of LipexSil™ 1 st
generation lipids in the transfection of GFP and Luciferase mRNA into cells with
accompanying low toxicity. Based on these successful transfection screening,investigation of further selected lipids is initiated to determine the transfection and
toxicity in the function of mRNA concentration.
2023 May
The dose-dependent transfection and toxicity experiments are successfully
completed. 5 best performer lipids are selected for in vivo studies on mice
(immunogenicity, transfection and toxicity studies).
Preliminary in vitro biological results of the selected LipexSil™ 2 nd generation lipids
prove their efficacy in the transfection of GFP and Luciferase mRNA into cells.
In a cooperation AldexChem Ltd. and Latvian LIOS file a FLPP grant application titled
“Application of catalytic hydrosilylation in the valorisation of renewables”.
2023 Augustus
In vivo studies on mice are initiated (immunogenicity, transfection and toxicity
studies).
First phase synthesis of LipexSil™ 2 nd generation lipids is completed which results
more than 30 new lipids.
