Natureza Inc. Develops the Solution to Drug Resistant Candida Auris and Pseudomonas Infections

Natureza Announcement July 14, 2023

Natureza carries out groundbreaking development of novel anti-infective agents. We have developed two agents that fulfil unmet healthcare needs for treatments against organisms with a high level of resistance to treatment agents. Together these represent a transformative breakthrough in the search for treatments against the growing worldwide threat of AMR.

  1. Active against Candida auris, formulated as a topical agent or lyophilised in an enteric coated capsule. Also suitable for use as a surface disinfectant. Potent activity in in vitro trials, stable formulations. Target indications are treatment of Candida auris infections and surface disinfection in healthcare environments.
  2. Active against Pseudomonas as single cells or in biofilms. Formulated as a lyophilised inhalable powder sized to penetrate to the alveoli in the lungs. This agent also shows anti-inflammatory activity in T cell models. Target indications are lung infections, early pulmonary fibrosis.

We are looking to license our patented agents for clinical development/co-development.

Characteristics of Natureza’s agents are:

  • No antibiotic resistance seen or developed on extended testing
  • Activity against WHO priority pathogens
  • Activity against multidrug resistant pathogens
    • Candida Auris
    • Pseudomonas
    • Carbapenem resistant Enterobacteriaceae
    • MRSA, VISA
  • Anti inflammatory activity in formulation PY-1, more effective than cyclosporine

Natureza Inc. is an offshoot of Biosafe Technologies Inc. which markets its head lice formula in the U.S. and Europe. Lynn James Meyer is the product developer, founder and CEO of Biosafe Technologies and Natureza. In Brazil in the early 1990’s several plant based derivatives were discovered to have insecticidal properties against ectoparasites. She developed a head lice treatment as part of her determination to introduce a natural, non-toxic solution. She subsequently returned to the US where, in 2000, she incorporated Biosafe Technologies, launched her product in the US and commenced further testing at Bristol University with a research specialist, Dr Coles, a Cambridge graduate and ScD who shared her commitment to making positive contributions to humanity. In 2003 she introduced her product in Europe where it still has wide distribution. In 2010 Mrs. James-Meyer appointed Dr Tristan Cogan Bsc (Hons) PhD, senior lecturer at the University of Bristol, UK as Natureza’s Anti-Microbial Project Manager. Their collaboration has led to the transformative advances against AMR described above.

Natureza Patents New Antibiotic Agents

Natureza Patents New Antibiotic Agents

  • Chitosan-coated carboxylic acids show antimicrobial activity against antibiotic-resistant Gram-negative and positive pathogens.
  • Our novel antibiotic agents show activity against some of the deadliest multi-drug resistant pathogens and there’s NO RESISTANCE.
Natureza Develops a Transformative New Class of Antibiotics that Overcomes Bacterial Resistance

Natureza’s patented formulations introduce a transformative new class of antibiotic agents that overcome bacterial resistance and removes the time barrier of investment return.

Natureza’s research offers a true paradigm shift, one that would remove the imbalance in development cost by eliminating the ability of bacteria to become resistant. With the promise of new drugs being able to be marketed for years providing not only the time to recover investment, but a profit as well, a new investment environment would emerge that would encourage the development of new, much needed antibiotics.

Lack of New Antibiotics Threatens Global Efforts to Contain Drug-Resistant Infections

“Never has the threat of antimicrobial resistance been more immediate and the need for solutions more urgent,” says Dr Tedros Adhanom Ghebreyesus, Director-General of WHO.
