We know that most of the bacteria are getting resistant to the present drugs and there is an urgent need to find a solution for resistant bacteria. Inn this global fight against resistant bacteria many companies are trying different ways and now Chaperone Technologies, Inc has come up with something innovative and interesting way, i.e., the company is trying to develop antimicrobial compounds that work by inhibiting bacterial hsp70 proteins (an entirely new mechanism of action).
Chaperone’s antimicrobial program focuses on development of peptide as well as small molecule hsp70 inhibitor drugs that block the effect of this important class of molecular “chaperones” whose role is to help mediate or respond to toxic misfolded proteins within bacteria. Inhibition of this critical bacterial protein has been proven to kill bacterial pathogens. Besides antimicrobials, the inhibition of hsp70 molecular chaperone proteins present in other cell-types has a range of therapeutic applications that are being investigated by the company.
Using sophisticated computerized molecular modeling techniques, proprietary high-throughput screening tools developed by Chaperone and other approaches, the company has significantly expanded its library of novel hsp70 inhibitor compounds including CHP-267 and CHP-281, just two of the many promising drug candidates from this highly promising family of small molecule inhibitors discovered by the Company. Chaperone is looking at hsp70 inhibitors as stand alone antimicrobial agents as well as in combination with other antimicrobials (e.g., Finafloxacin.HCl : see the structure -which is under phase II clinical trials). The company recently received a US Patent covering a method of significantly amplifying the effectiveness of other antimicrobials by combining their use with that of an hsp70 inhibitor. Combining a bacterial hsp70 inhibitor with another antimicrobial yields increased bacterial killing of clinically important pathogens and the potential for combination therapy.
Chaperone’s drug candidates have been proven effective against dangerous bacteria such as MRSA, acinetobacter, and vancomycin resistant enterococci. When combined with other antibiotics, Chaperone’s compounds stimulate powerful antibiotic synergy, providing superior efficacy even while using significantly lower doses of the combined agents.
