Increased environmental consciousness coupled with detrimental impacts of synthetic dyes and consumers’ concern over hygiene, cleanliness and protection, the demand for functional textiles has increased in recent years. Antimicrobial finishing imparts protective properties to textiles besides attractive shades. The study was aimed to determine the antifungal activity of colourants from aerial biomass of Perilla frutescens and dyed fabrics against pathogenic fungi infesting textiles materials. Antifungal activity of natural dye extracted from aerial biomass of Perilla frutescens against the selected pathogenic fungi viz., Aspergillus niger, Aspergillus flavus, Fusarium moniliforme, Fusarium solani, and Penicillium decumbens was evaluated by agar-well diffusion method. The MIC of the natural dye against each of the test fungi was determined by broth dilution method. Dyed silk, wool and cotton fabrics were also evaluated for antifungal activity by standard method. The natural dye showed antifungal activity against all the five test fungi in a concentration dependent manner. The treatment dose of 1000μg/ml recorded the highest growth reduction in all the test fungi, nearly at par with the positive control. The MICs of natural dye against the test fungi ranged from 32.39 to 36.50μg/ml. All kinds of dyed fabrics also showed remarkable antifungal efficacy against the test fungi. Dyed wool fabric exhibited the maximum growth reduction followed by silk and cotton. The result of the study demonstrated the remarkable antifungal activity of natural dye from Perilla frutescens aerial biomass and dyed fabrics. Therefore, Perilla frutescens can be considered as a potential source of natural dye with functional properties and can be used in protective finishing of different kinds of textile fabrics.

Fungicidal activity of 10 ethnobotanically known Kumaun Himalayan gymnospermous plants namely Araucaria cunninghamii, Biota orientalis, Cedrus deodara, Cephalotaxus griffithi, Cryptomeria japonica Cupressus torulosa, Ginkgo biloba, Juniperus communis, Picea smithiana and Pinus wallichiana were tested against six plant disease causing fungal pathogens by agar well-diffusion method. Forty extracts of these gymnospermic leaves in different organic solvents (methanol, ethanol, chloroform and hexane) were studied by performing the 160 sets of experiments. The MIC values of each extract (where % inhibition ≥ 40%) were also determined. All the plant extracts exhibited strong antifungal activity. Results indicated that all leaves extracts of C. griffithi and G. biloba were found most effective among the tested plants extracts. Hexane extract of C. griffithi was showed highest inhibitory activity against C. falcatum (72%; MIC, 7.81µg/ml) and T. indica (70%; MIC, 15.62µg/ml). On the other hand, ethanol extract of G. biloba also showed remarkable activity against P. oryzae (66% with MIC, 7.81g/ml). While P. wallichiana leave extracts were found less active among the studied plants against all the tested fungal strains. The chloroform extracts were found the most effective against all the tested fungi (10% to 60%), followed by ethanol extract (30-50%), methanol extract (20-40%), while in hexane extracts ranged 10-30% only. The extracts of C. griffithi exhibited superior Relative Antifungal Activity (RAA, 20%), followed by G. biloba and A. cunninghamii (RAA, 19 and 12%, respectively). All data were also analyzed for determination of total activity of plant for each studied species of gymnosperm. C. griffithi had maximum activity i.e. 71 % followed by G. biloba (54%) and A. cunninghamii (33%). C. torulosa showed the least total activity and RAA i.e. 8% and 3%, respectively. All the plant species assayed possess definite antifungal properties and suggested for phytochemical analysis to identify the active principles responsible for their antifungal activity

Background. Echinops kebericho is an endemic medicinal plant in Ethiopia widely used in the treatment of infectious and noninfectious diseases. Essential oils are known for their antibacterial, antifungal, antiviral, insecticidal, and antioxidant properties. This study evaluated the antifungal activity of essential oil from E. kebericho against four common pathogenic fungi and two standard strains. Methods. The essential oil was obtained by hydrodistillation. The antifungal screening was done by agar well diffusion method. Minimal inhibitory concentrations (MICs) were determined by broth microdilution. Minimal fungicidal concentrations (MFCs) were determined by subculturing fungal strains with no visible growth onto a Sabouraud dextrose agar (SDA) plate. Results. Candida albicans and Cryptococcus neoformans were highly sensitive while Aspergillus flavus did not show sensitivity up to 1 mg/ml of essential oil; MICs ranged from 0.083 mg/ml to 0.208 mg/ml. Concentration and fungal species showed significant dose-dependent associations ( p < 0.0001 ) with antifungal activity. The MICs of essential oil were comparable to those of the standard drug (fluconazole) against C. glabrata and C. krusei. The lowest MFC of the essential oil was observed against Candida parapsilosis (0.145 mg/ml) while the highest MFC was against Candida krusei (0.667 mg/ml). Conclusion. Echinops kebericho essential oil showed noteworthy antifungal activity against Cryptococcus neoformans, Candida albicans, and Candida glabrata and could be a potential candidate for further antifungal drug development.

ABSTRACT NC1175 (3-[3-(4-chlorophenyl)-2-propenoyl]-4-[2-(4-chlorophenyl)vinylene]-1-ethyl-4-piperidinol hydrochloride) is a novel thiol-blocking conjugated styryl ketone that exhibits activity against a wide spectrum of pathogenic fungi. Incubation of NC1175 with various concentrations of cysteine and glutathione eliminated its antifungal activity in a concentration-dependent fashion. Since NC1175 is a lipophilic compound that has the potential to interact with cytoplasmic membrane components, we examined its effect on the membrane-located proton-translocating ATPase (H+-ATPase) of yeast (Candida albicans, Candida krusei,Candida guilliermondii, Candida glabrata, andSaccharomyces cerevisiae) and Aspergillus(Aspergillus fumigatus, Aspergillus niger,Aspergillus flavus, and Aspergillus nidulans) species. The glucose-induced acidification of external medium due to H+-ATPase-mediated expulsion of intracellular protons by these fungi was measured in the presence of several concentrations of the drug. NC1175 (12.5 to 50 μM) inhibited acidification of external medium by Candida, Saccharomyces, andAspergillus species in a concentration-dependent manner. Vanadate-inhibited hydrolysis of ATP by membrane fractions of C. albicans was completely inhibited by 50 μM NC1175, suggesting that the target of action of NC1175 in these fungi may include H+-ATPase.

Aim: This work was carried out to determine the chemical compositions of Ocimum gratissimum leaf (Fig. 1) using GC-MS and its antifungal potential against some plant pathogenic fungi. Study Design: The study was designed to determine its chemical compositions by GC-MS and to test the inhibitory ability of the plant extract on plant pathogens. Place and Duration of Study: Department of Chemistry, Alvan Ikoku Federal College of Education, Owerri and Department of Plant Science and Biotechnology, Imo State University, Owerri, Nigeria, between February to July 2017. Methodology: The ethanol extract of the leaf of Ocimum gratissimum was evaluated using GC-MS to determine the chemical compositions of the plant. The identification of compounds was done by comparing spectrum of the unknown component with the spectrum of the known components stored in the NIST library. The essential oil of the plant was used to analyze the antifungal potential of the plant. This was done against some plant pathogenic fungi using disc diffusion method and MIC using broth micro dilution method. Results: The GC-MS analysis revealed eight compounds (Fig. 2) with n- Hexadecanoic acid constituting the bulk of the oil (37.21%), followed by Oleic acid (25.38%) and Octadecanoic acid (16.19%). Other compounds present in the plant are Glycyl alcohol (2.47%), Methyl alpha –D- Glucopyranoside (8.33%), Tetradecanoic acid (5.77%), Palmitic amide (2.72%) and d-Glucose, 2,3- diethyl-4,5-dithioacetyl (1.93%). Ocimum gratissimum exhibited different degrees of antifungal activity against the mycelial growth of Aspergillus niger, Botryodiploidia theobromae, Rhizopus stolonifer, Penicillium expansum and Colletotrichum spp and Fusarium oxysporium. The maximum percentage degree inhibition of Ocimum gratissimum oil was observed on A. niger at different concentrations while the least inhibition was observed in Colletotrichum spp at different concentrations. Analysis of some of the compounds found in Ocimum gratissimum such as Methyl alpha.-d-glucopyranoside, Oleic acid etc, reveals the rich pharmacological potential of this medicinal plant and the inhibitory potential of the plant against fungi justify the use of Ocimum gratissimum as a medicine traditionally.

The rapid increase in the number of multidrug-resistant of most pathogenic organisms is fast becoming a global concern, thus, the discovery of novel active pharmacological compounds against new targets is a matter of urgency. The incorporation of metal ions into organic ligands has introduced metal-organic drugs framework with synergistic effects for novel applications in the biological system. In this research work, metal(II) chloride complexes of copper, nickel and zinc containing methylphenylketone thiosemicarbazone (MPK-TSC) with 2,2’-bipyridine (bipy) were synthesized; they were further characterized by satisfactory microelemental analysis, Fourier Transform InfraRed (FTIR) spectra as well as electronic spectra study. The complexes are proposed to have the formulae [L1ML2(Cl2)] where M=metal ion, L1=methylphenylketone thiosemicarbazone   L2=2,2’-bipyridine. The complexes are of 1:2 (metal:ligand) stoichiometry and non-electrolytes in solution, the bidentate nature of the two ligands was evident from the FTIR spectra. The compounds were screened for their antifungal activity against four pathogenic fungi: Aspergillus niger, Penicillium Species, Rizopus and Candida albicans using disc diffusion method. The activities of the complexes have been found to be greater than those of the metal salts and the uncoordinated ligands.
