Background: Fungal infections have always remain a problem and they are getting worse with passage of each year due to their resistance against available antibiotics. Natural ways of treatment with homoeopathic medicines made of mother tinctures of plants have no reported side effects and have been proved effective against many bacterial and fungal infections. Materials & Methods: Preparation of mother tinctures of plants Cressa cretica, Leptadenia pyrotechnica and Pulicaria crispa was done and used to evaluate the anti-fungal potential of these plants against potentially pathogenic fungal species like Aspergillus niger, Aspergillus flavus, Aspergillus ustus and Candida albicans by agar disc diffusion method. Each tincture was evaluated at 0.25 ml, 0.5 ml and 1 ml volume per disc and zone of inhibition was measured in millimetres and compared with commercial drug Fluconazole (2 mg/ml) which was used as standard. Results: The results showed that satisfactory anti-fungal activity of these plants in comparison to standard drug Fluconazole. The ratio of antifungal activity of Cressa cretica measured as the zone of growth inhibition of these cultures against Aspergillus niger, Aspergillus flavus, Aspergillus ustus and Candida albicans was 24 mm / 27 mm, 30mm / 28 mm, 23 mm/ 30 mm and 32 mm/ 30 mm respectively. In the case of Leptadenia pyrotechnica, the mother tincture’s antifungal activity was 32 mm / 27 mm, 30 mm / 28 mm, 17 mm/ 30 mm and 24 mm/ 30 mm. In case of our third plant Pulicaria crispa, antifungal activity came out to be 23 mm/ 27 mm, 26 mm/ 28 mm, 26 mm / 30 mm and 24 mm/ 30 mm. Conclusion: Our study proved that mother tincture of these plants can be a potential new therapy to treat fungal infections and has the potential to rule out fungal problems. Further research using mother tincture of these plants against other fungal species has the potential to prove them a safer and widespread anti-fungal homoeopathic medicine.

Acalypha Indica

Anti-microbial and anti-fungal activity of different solvent extracts of Acalypha indica (Euphorbeace family) was tested against bacterial pathogens (Pseudomonasaeruginosa, E.Coli, KlebsiellaPneumonia and Staphylococcus aureus) and fungal strains (Candida albicans, Aspergillus niger, Candida tropicalis andCandida kefyr) using the Agar Well diffusion method . It was observed that all the extracts showed positive activity) against bacteria and fungi. Ethanolic extract of Acalypha indica showed more potency against Staphylococcus aureus with an inhibition zone of12.46 (mm) and Methanolic extract exhibited higher activity against E.coli with an inhibition zone of11.26 (mm). Ethanolic extract of Acalypha indica showed prominent antifungal activity against candida albicans with an inhibition diameter of 12.53 (mm) and Aspergillus niger with a diameter of 9.21 (mm) when compared to other solvent extracts. Erythromycin and Ketoconazole were used as positive standards for antimicrobial and anti fungal experiments. In the present study, Ethanol extract showed a varying degree of inhibition to the growth of tested organisms compared to Methanol, Acetone and Chloroform against Bacteria and Fungi. The results confirmed the presence of antibacterial and antifungal compounds in shade dried extracts of Acalypha indica against human pathogenic organisms.

Several 6- and 7-alkoxy-2-oxo-2H-chromene-4-carbaldehydes were prepared from corresponding alkyl ethers of 6- and 7-hydroxy-4-methyl-2-oxo-2H-chromen-2-ones by oxidation using selenium dioxide. 6- and 7-Alkoxy-4-methyl-2H-chromenes were obtained with yields of 57-85%. Corresponding 4-carbaldehyde derivatives were prepared with yields of 41-67%. Thiosemicarbazones of these aldehydes with D-galactose moiety were synthesized by reaction of these aldehydes with N-(2,3,4,6-tetra-O-acetyl-β-Dgalactopyranosyl) thiosemicarbazide with yields of 62-74%. These thiosemicarbazones were screened for their antibacterial and antifungal activities in vitro against bacteria, such as Staphylococcus aureus, Escherichia coli, and fungi, such as Aspergillus niger, Candida albicans. Several compounds exhibited strong inhibitory activity with MIC values of 0.78- 1.56 μM, including 8a (against S. aureus, E. coli, and C. albicans), 8d (against E. coli and A. niger), 9a (against S. aureus), and 9c (against S. aureus and C. albicans).

This Research on the antibacterial and antifungal activity of nanosilver against Neisseria gonorrhoeae and Candida albincas fungi has been carried out. The purpose of this study was to determine antibacterial activity of nanosilver against Neisseria gonorrhoeae and antifungal activity against Candida albincas. Synthesis Nanosilver uses bottom up method and characterized using UV-Vis Spectrophotometer. Nanosliver concentrations used were 30, 40, 50, and 60 ppm. Antibacterial and antifungal activity tests using disk diffusion method. Observations obtained in form of the presence or absence of clear zones formed around paper discs indicate the inhibition of nanosilver on microbial growth. The results of testing the antifungal activity of Candida albicans on nanosilver with concentrations of 30, 40, 50 and 60 ppm resulted in clear zones of 9.73 nm, 11.46 nm, 11.93 nm, and 13 nm with fungal inhibition response categories is medium and strong. The results antibacterial activity test of Neisseria gonorrhoeae on nanosilver with concentrations of 30, 40, 50 and 60 ppm did not show any clear zone around the disc, it showed that nanosilver in this study did not have antibacterial activity against Neisseria gonorrhoeae.

Quinazoline Derivatives

The emergence of multidrug microbial resistance is the main challenges that the modern scientists have so far been facing in the recent era. In this respect, new series of drug classes having potential to give antimicrobial effect have been synthesized. A new series of 5- substituted-1,10 b-dihydroimidazole[1,2-c]quinazoline derivatives 8a-e have been synthesized and screened for antibacterial activity and antifungal activity. Synthesized derivatives were characterized by IR, MASS and 1H-NMR spectroscopy. Synthesized compounds show good activity, which was comparable to the standard drug and it can be useful for the further clinical study. Antibacterial activity was evaluated against four different pathogenic bacterial strains like Staphylococcus aureus, Enterococcus faecalis, Escherichia coli and Pseudo-monas aeruginosa. Among the screened compounds, 8e show good antibacterial activity against Staphylococcus aureus and Escherichia coli with MIC of 50 and 100 μg/ml respectively. Antifungal activity was evaluated  against two strains of fungi. Among the synthesized derivates, compound 8c was emerged out as the potent antifungal compound against Candida albicans and Aspergillus niger with MIC of 25 μg/ml and 75μg/ml respectively. Compound 8e also shows good antifungal activity with MIC of 50 μg/ml against both Candida albicans and Aspergillus niger. The overall results of this study indicated that  synthesized quinazoline derivatives had the potential to act as an antibacterial and antifungal agent, hence further investigation is warranted.

Antibacterial activities of different extracts of epiphytic orchids were tested against 5 species of bacteria and antifungal activities were tested against 3 species of fungi. All orchid extracts showed good bacterial Zone of Inhibition (ZOI) against Staphylococcus aureus. The crude extracts of Pholidota imbricata and Coelogyne cristata were shown highest activity against Vibrio cholerae and Staphylococcus aureus respectively. The MIC and MBC value of the extracts of Pholidota imbricata and Coelogyne cristata were found to be 62.5 mg/ml, 31.25 mg/ml and 125 mg/ml, 250 mg/ml against Vibrio cholerae and Staphylococcus aureus respectively. Only Pholidota imbricata and Pholidota articulata extracts were shown fairly good activity but all others extracts were shown very less activity or even failed to show any activity against fungal organisms.DOI: http://dx.doi.org/10.3126/jncs.v29i0.9259Journal of Nepal Chemical Society Vol. 29, 2012 Page: 104-109 Uploaded date: 12/5/2013
