The structure of compound 1 was elucidated by 1D and 2D NMR analyses which included HSQC, HMBC, and nuclear overhauser effect spectroscopy (NOESY) experiments as well as X-ray crystallography. This is the first report of phyllocladane diterpenes from genus Anisomeles. Compounds 1, 3, 4, and 5 were evaluated for inhibition of Mycobacterium tuberculosis and 3 was found to exhibit anti-mycobacterial activity with IC90 6.53 mu g/ml. Compounds 1, 3, and 5, at 100 mu g/ml, were also evaluated for inhibition of Thp-1 cell lines, and compounds 1 and 3 showed 59.02% and 96.4% inhibitions, respectively.</p>10aAnisomeles heyneana10aLamiaceae10aMycobacterium tuberculosis10aphyllocladane diterpenes1 aKulkarni, Roshan, R.1 aShurpali, Ketaki1 aGawade, Rupesh, L.1 aSarkar, Dhiman1 aPuranik, Vedavati, G.1 aJoshi, Swati, P.  uhttps://library.ncl.res.in/content/phyllocladane-diterpenes-anisomeles-heyneana-002489nas a2200277   4500008004100000022001400041245016500055210006900220260006700289300001000356490000800366520147900374653001401853653002101867653001501888653001501903653001901918653002801937100001701965700002101982700001602003700001702019700002102036700002602057856012802083       2015                        eng d  a1364-507200aPossible mechanism of antifungal phenazine-1-carboxamide from pseudomonas sp against dimorphic fungi Benjaminiella poitrasii and human pathogen Candida albicans0 aPossible mechanism of antifungal phenazine1carboxamide from pseu  a111 RIVER ST, HOBOKEN 07030-5774, NJ USAbWILEY-BLACKWELLcJAN  a39-480 v1183 a<p>AimInvestigation of antifungal mechanism of phenazine 1-carboxamide (PC) produced by a Pseudomonas strain MCC2142. Methods and ResultsAn antifungal metabolite produced by a Pseudomonas was purified and identified as PC. Human pathogenic fungi such as Candida albicans, Candidaglabrata, Cryptococcus neoformans, Fusarium oxysporum, Aspergillus fumigatus and Aspergillus niger were found to be inhibited by PC (MIC90 32-64gml(-1)). Addition of PC (20gml(-1)) during yeast (Y)-hypha (H) transitions inhibited germ tube formation by &gt;90% and &gt;99% in C.albicans National Collection of Industrial Microorganisms (NCIM) 3471 and nonpathogenic model Benjaminiella poitrasii, respectively. After exposure to PC (20gml(-1)), 75-80% yeast cells of B.poitrasii and C.albicans NCIM 3471 showed rhodamine 123 fluorescence indicating high intracellular reactive oxygen species (ROS) production. ROS further led to hyperpolarization of mitochondrial membrane, subsequently induction of apoptosis as evident by externalization of phosphatidylserine, DNA fragmentation, chromatin condensation and finally death in B.poitrasii. In C.albicans NCIM 3471, PC (20gml(-1)) induced apoptosis. ConclusionsThe antifungal effect of PC in B.poitrasii and C.albicans may be due to ROS-mediated apoptotic death. Significance and Impact of the StudyInhibition of Y-H transition of B.poitrasii and C.albicans by PC indicates that it may prove useful in the control of dimorphic human pathogens.</p>10aApoptosis10aCandida albicans10adimorphism10aphenazines10aPseudomonas sp10areactive oxygen species1 aTupe, S., G.1 aKulkarni, R., R.1 aShirazi, F.1 aSant, D., G.1 aJoshi, Swati, P.1 aDeshpande, Mukund, V.  uhttps://library.ncl.res.in/content/possible-mechanism-antifungal-phenazine-1-carboxamide-pseudomonas-sp-against-dimorphic-0
