Misitura Lawal-Arowona Develops Anti-Tuberculosis Metal Drug

Mrs. Misitura Lawal-Arowona, a PhD scholar with the University of Ilorin and a lecturer at Kebbi State University has successfully developed metal attached anti-tuberculosis drug.

According to a report published in the Sunday Times of India, under a sandwich fellowship at Faculty of Science of The Maharaja Sayajirao University (MSU) of Baroda, India, Mrs. Misitura Lawal-Arowona, under the supervision of Professor Joshua Obaleye, has promised to tackle the menace of tuberculosis (TB) with the drug both in African countries as well as India.

This has improved the efficiency of the anti-tuberculosis drugs compared to normal drugs that are consumed globally.

Nigeria is among the 14 high burden countries for TB, TB/HIV and multi-drug resistant TB. The country is ranked seventh among the 30 high TB burden countries and second in Africa The problem of TB in Nigeria has been made worse by the issues of drug resistant TB and the HIV/AIDS epidemic.

According to Mrs. Misitura Lawal-Arowona, who is in Vadodara for a year-long project:

“Earlier, studies have proved that when a metal is attached with a pharmaceutical, it increases efficacy of the drug.” 

Taking a cue from cisplatin, an anti-cancer drug, whose efficacy improved after applying platinum as metal, the scholar worked on multiple metal-based drugs to see whether efficiency of anti-TB drugs can be increased by attaching metals to it.

She used metals like ion, cobalt, copper and zinc to prepare the metallodrugs. The drugs, which have been developed, include ciprofloxacin HCl, ofloxacin, pyrazinamide and moxifloxacin HCl.

Presently, there is no metal-based anti-TB drug available in the market.

According to Professor Rajendrasinh Jadeja from MSU’s chemistry department, who is mentoring Mrs. Misitura Lawal-Arowona:

“When we compared the metallodrugs with the original anti-TB drugs, the metallodrugs were more effective.

We did in vitro test against bacteria. The metal we have chosen are non-harmful to human beings. Also, we found that of all the metallodrugs, the copper complex of ciprofloxacin is most effective.”

Mrs. Misitura Lawal-Arowona is pursuing her research at MSU under fellowship sanctioned by the Italy-headquartered Third World Academy of Sciences and Department of Biotechnology, Government of India.
