We pioneered the concept of utilizing sugar alcohol (SA) monomers to chemically assemble proprietary AqT™
molecules with properties by design. AqT™ molecules are super-hydrophilic molecules and
have many advantages over classical linkers and polymers, such as PEG and PLGA, in terms of improved a) hydrophilicity, b) biodegradability, c) loading,
d) versatility, and e) easy of customization. AqT™ linkers and biopolymers are by far the most
pure, hydrophilic, and versatile conjugation and delivery molecules available in development.
We can effectively synthesize any AqT™ molecule with superior properties that benefit
the resulting hybrid drug, such as higher loading, super-hydrophilicity, and biodegradability. This
flexibility in the AqT™ chemistry cannot be matched by any other existing linker and polymer
technologies due to the inherent versatile nature of SA monomers and the modular approach of our chemistry.
The current focus of novel AqT™ architectures is target-specific drug delivery,
combination treatment, and enhancing the therapeutic profiles of stand-alone drugs.
