Sirona Biochem Receives Antiviral Testing Results
Vancouver, Canada – Nov 29, 2023 – Sirona Biochem Corp. (TSX-V: SBM) (FSE: ZSB) (OTC: SRBCF)
(“Sirona”) announces the results of its research collaboration with the International Centre for Genetic
Engineering and Biotechnology (“ICGEB”) in advancing Sirona’s antiviral compound library.
The ICGEB has completed a successful screening of a second compound library from Sirona’s subsidiary
TFChem, evaluating its potential as inhibitors of SARS-CoV2. The library, comprised of 18 novel
compounds, underwent testing at the ICGEB’s Laboratory of Molecular Virology in Trieste, Italy. The testing
was led by Dr. Alessandro Marcello, an internationally recognized expert in Human Virology. Among the 18
compounds, four exhibited notable antiviral activity.
The results of the testing and the selective index, which gauges potency versus toxicity, does not currently
identify a lead compound. Consequently, the 38 compounds synthesized so far are not considered
candidates for developing a treatment for SARS-CoV2 in humans. Sirona will be reviewing its collaboration
agreement with the ICGEB after further discussions. Potential options include testing the compounds
against other pathogenic viruses and also analyzing their effect on living cells to confirm their targeted
mechanism of action. Standardized testing procedures are available for these assessments.
"Although these results may not endorse a potential treatment for SARS-CoV2, Dr. Howard Verrico, CEO,
emphasizes the significance of further testing to assess the potential in the broader battle against other
pathogenic viruses. The absence of potent antivirals for numerous classes of pathogenic viruses
underscores the significance of this project as a worthwhile endeavor. He notes, 'The timing of additional
testing will be determined through further assessment and expert consultations. '
Sirona is currently driving forward with compelling developments in its pipeline, giving precedence to
initiatives aimed at sparking near-term revenue growth. Expect updates on these initiatives, which will be
shared as soon as they progress to more advanced stages of planning. The company maintains an
optimistic outlook, fueled by enthusiasm for the promising prospects that lie ahead in its ongoing ventures."
About the International Centre for Genetic Engineering and Biotechnology
Established in 1983 as a special project of UNIDO, the International Centre for Genetic Engineering and
Biotechnology - ICGEB is an independent intergovernmental organization with HQ in Trieste (Italy) and with
additional laboratories in New Delhi (India) and Cape Town (South Africa). It counts almost 70 Member
States. The ICGEB is a not for profit IGO – any revenues generated are re-invested in research and in the
funding programs for capacity building in its Member States. The Vision of the ICGEB is to be the world’s
leading intergovernmental Organization for research, training, and technology transfer in the field of Life
Sciences and Biotechnology. Its Mission is to combine scientific research with capacity enhancement,
thereby promoting sustainable global development (https://www.icgeb.org/).
The Molecular Virology Group in Trieste studies the detection and molecular mechanisms of different
arboviruses and has been mainly involved in the response to the COVID-19 pandemic providing support to
the ICGEB Member countries. Activities included in the formulation for protocols for SARS-CoV-2 molecular
and serological diagnostics, online tutorials and reagents to be able to develop low-cost in-house assays.
COVID-19 viruses circulating in several countries have been sequenced for the first time and made
available to the scientific community. A pipeline for testing antivirals against SARS-CoV-2 has been set-up
allowing the identification of novel drug candidates.
