In vitro, ex vivo and in vivo anti-hypertensive activity of Chrysophyllum cainito L. extract.

ABSTRACT: Chrysophyllum cainito L., a traditional herbal medicine, could have the potential for management of hypertension due to presence of polyphenolic compounds. The extracts and fractions of the pulp of plant were evaluated for in vitro (inhibition of angiotensin I converting enzyme/ACE assay), ex vivo (isolated aorta relaxation assay) and in vivo (salt induced hypertensive rat assay). The alcoholic and aqueous extract (ALE and AQE respectively) of fruit of plant C. cainito was having 14.8 and 9.2% yield respectively. The fractionation with ethyl alcohol (EAF) and butanol (BTF) yielded 2.52 & 2.17% respectively from ALE and 0.46 & 0.31% respectively from AQE with respect to fruit pulp dry weight. More phenolic content was found in ALE (3.75±0.15 mg gallic acid equivalent or GAE g(-1) of dry power of fruit pulp) compared to AQE and maximum in ethyl acetate fraction of ALE (ALE-EAF) (2.32±0.21 mg GAE g(-1) of dry power of fruit pulp) among all fractions. ACE inhibition activity was found to be maximum in ALE-EAF 62.5±7.34%. While ex vivo study using isolated tissue of aorta showed again showed maximum activity (62.82±6.19 and 46.47±8.32% relaxation with 50 µg mL(-1) and 10 µg mL(-1) GAE concentration respectively). ALE-EAF reduced the elevated arterial pressure of salt induced hypertensive rat significantly to the level of normotensive animal group. Results of ALE-EAF have shown its potential as a source for novel constituent for the treatment hypertension and should further be studied for isolation of specific constituent for more effectiveness.

Project description:Gonorrhea remains a major global public health problem because of the high incidence of infection (estimated 82 million cases in 2020) and the emergence and spread of Neisseria gonorrhoeae strains resistant to previous and current antibiotics used to treat infections. Given the dearth of new antibiotics that are likely to enter clinical practice in the near future, there is concern that cases of untreatable gonorrhea might emerge. In response to this crisis, the World Health Organization (WHO), in partnership with the Global Antibiotic Research and Development Partnership (GARDP), has made the search for and development of new antibiotics against N. gonorrhoeae a priority. Ideally, these antibiotics should also be active against other sexually transmitted organisms, such as Chlamydia trachomatis and/or Mycoplasma genitalium, which are often found with N. gonorrhoeae as co-infections. Corallopyronin A is a potent antimicrobial that exhibits activity against Chlamydia spp. and inhibits transcription by binding to the RpoB switch region. Accordingly, we tested the effectiveness of corallopyronin A against N. gonorrhoeae. We also examined the mutation frequency and modes of potential resistance against corallopyronin A. We report that corallopyronin A has potent antimicrobial action against antibiotic-susceptible and antibiotic-resistant N. gonorrhoeae strains and could eradicate gonococcal infection of cultured, primary human cervical epithelial cells. Critically, we found that spontaneous corallopyronin A-resistant mutants of N. gonorrhoeae are exceedingly rare (≤10-10) when selected at 4× the MIC. Our results support pre-clinical studies aimed at developing corallopyronin A for gonorrheal treatment regimens. IMPORTANCE The high global incidence of gonorrhea, the lack of a protective vaccine, and the emergence of N. gonorrhoeae strains expressing resistance to currently used antibiotics demand that new treatment options be developed. Accordingly, we investigated whether corallopyronin A, an antibiotic which is effective against other pathogens, including C. trachomatis, which together with gonococci frequently cause co-infections in humans, could exert anti-gonococcal action in vitro and ex vivo, and potential resistance emergence. We propose that corallopyronin A be considered a potential future treatment option for gonorrhea because of its potent activity, low resistance development, and recent advances in scalable production.
