Anti-cancer agents in medicinal chemistry | Year: 2017

The chemistry of heterocyclic containing, 1,3,4-thiadiazole has been an interesting field of study from ancient years. Subsequently, 1,3,4-thiadiazole nucleus constitutes a significant class of compounds for new drug development. Recently, various 1,3,4-thiadiazole derivatives synthesized and evaluated their biological activities including antimicrobial, antituberculosis, antioxidant, anti-inflammatory, anticonvulsants, antidepressant and anxiolytic, antihypertensive, anticancer and antifungal activity. The search for anticancer compounds with more selective activities and lower side effect continues to be an active area of argument examination in medicinal chemistry. This review elaborately described the medicinal chemistry, their structural activity relationship, and anticancer properties with respect to human cell line based approach related to synthesized 1,3,4-thiadiazole derivatives.

CdS nanocrystalline materials have been prepared by reaction of Cd(II) ions with an alkaline solution of thiocarbamide in the aqueous solution phase. The effect of reaction time and surfactants (cetyltrimethyl ammonium bromide (CTAB), sodium dodecyl sulfate (SDS)) on morphology and size of the products has been investigated. Dramatic shape and size variations have been observed by varying the surfactant and reaction time. CdS nanocrystals formed in various reactions were characterized by X-ray diffraction (XRD), scanning electron microscopy (SEM), energy dispersive X-ray spectroscopy (EDX), and transmission electron microscopy (TEM) to determine the crystallinity, phase, composition, size, and morphology. The optical properties of the thus prepared samples were determined by UV-vis absorption spectra. A possible formation mechanism of CdS nanocrystals has also been discussed in this article. © 2011 American Chemical Society.

Abundance of naturally growing Azolla caroliniana (water fern) on the surface of metal enriched fly ash (FA) pond reflects its toxitolerant characteristics. Results indicate the efficiency of A. caroliniana for phytoremediation of FA pond because of its higher bioconcentration factor. The metal concentration ranged from 175 to 538 and 86 to 753mgkg-1 in roots and fronds, respectively. Bioconcentration factor (BCF) values of all metals in root and frond ranged from 1.7 to18.6 and 1.8 to 11.0, respectively, which were greater than one and indicates the metal accumulation potential of A. caroliniana. Translocation factor (TF) ranged from 0.37 to 1.4 for various heavy metals. The field result proved that A. caroliniana is a potential accumulator for the examined heavy metals and can be used for phytoremediation of FA pond. © 2012 Elsevier Inc.

The indiscriminate application of synthetic chemicals in agriculture has deteriorated extremely the quality of environment due to loss of beneficial microbial communities. The world now has a real prospect to grow sustainably and eliminate acute food scarcity in the next generation. Achieving this will require eco-friendly and safe technology for restoration of degraded lands. Microbes form the vital living components of soils contributing ecosystem sustainability due to their cosmopolitan survival, massive efficient genetic pool, catabolic versatility and stress tolerance potential. It has been reported that direct application of modified microbes enhances the microbial diversity in the agro-ecosystems by breaking dormancy of inactive soil microbial pool. It is presumed that enhanced diversity of efficient microbial community compositions in degraded ecosystems establish a functional equilibrium, which help maintain sustainability. Undoubtedly therefore, microbes may play the role of chief ecological engineers in resolving the environmental problems as well as the innovative tool to reinstate the degraded ecosystems. © 2015 Elsevier B.V.

The present study reports the influence of different factors on the sorption of Pb and Cd by Nostoc muscorum. The results showed that extent of Pb and Cd removal by N. muscorum cells increased with increasing biosorbent dose, but exhibited decline in the adsorption capacity. The maximum sorption of Cd (85.2%) and Pb (93.3%) was achieved at 60 and 80 microg/ml concentrations of respective metal, within 30 and 15 min, respectively. The result revealed that optimum biosorption of Pb and Cd occurred at pH 5 and 6, respectively, at 40 degrees C temperature. Presence of binary metals (both Pb and Cd) in a solution showed that the presence of one metal ion resulted into decreased sorption of other metal ion. The presence of Ca and EDTA showed significant decrease in the sorption of Pb and Cd, while other anions and cations did not show significant effect on the biosorption of both the metals. Maximum desorption of Pb and Cd was achieved in the presence of EDTA and HNO3, respectively. Results also showed that the test biosorbent could be repeatedly used up to six biosorption/desorption cycles without significant loss of its initial metal adsorption capacity.

In the present study, double-diffusive convection in an anisotropic porous layer with an internal heat source, heated and salted from below, has been investigated. The generalized Darcy model is employed for the momentum equation. The fluid and solid phases are considered to be in equilibrium. Linear and nonlinear stability analyses have been performed. For linear theory normal mode technique has been used, while nonlinear analysis is based on a minimal representation of truncated Fourier series. Heat and mass transfers across the porous layer have been obtained in terms of Nusselt number Nu and Sherwood number Sh, respectively. The effects of internal Rayleigh number, anisotropy parameters, concentration Rayleigh number, and Vadasz number on stationary, oscillatory, and weak nonlinear convection are shown graphically. The transient behaviors of Nusselt number and Sherwood number have been investigated by solving the finite amplitude equations using a numerical method. Streamlines, isotherms, and isohalines are drawn for both steady and unsteady (time-dependent) cases. The results obtained, during the above analyses, have been presented graphically, and the effects of various parameters on heat and mass transfers have been discussed. © 2011 Springer Science+Business Media B.V.

An increasing area of fly ash (FA) disposal and its toxicity have become a global concern due to the proliferation of coal-fired power plants, which contaminate the ecosystems of our earth. In this regard, many plants are suggested for phytoremediation of FA disposal sites, but there is a dearth of studies regarding commercial crop-based phytoremediation having a range of economic and ecological services. Therefore, the present investigation was focused to examine phytoremediation potential of naturally grown industrial crop Ricinus communis L. on FA polluted sites. The bioconcentration factor value of all metals in the root of R. communis L. was greater than 1 which indicates the metal accumulation potential of this crop. Translocation factor value of all the metals was found less than 1, which shows that these metals are stabilized in the root part of the plant. Furthermore, being industrial oil yielding crop and unpalatable, R. communis L. is a potential candidate for FA phytoremediation along with its economic and ecological values. Thus, R. communis L. can be used as a commercial crop for phytostabilization and revegetation of FA disposal sites in tropical and sub-tropical region. Besides the stabilization of heavy metals, FA revegetation provides other hidden benefits such as carbon sequestration, substrate quality enhancement, esthetically pleasant landscape, multipurpose oilseed production and biodiversity conservation. © 2013 Elsevier B.V.

The present investigation was focused to examine the phytoremediation potential of naturally grown Ipomoea carnea on fly ash (FA) deposits. I. carnea is an invasive species and mostly neglected by people but it has unusual characteristics which deals to phytoremediation. The metal accumulation of Cd, Pb, Cu, Cr, Mn and Ni ranged from 5.3 to 39.7, 7.4 to 30.6, 19.9 to 32.5, 9.5 to 20.6, 19.0 to 90.1, and 13.7 to 68.2μgg-1, respectively, in all the parts of I. carnea grown on barren FA deposits during two periods (pre- and post-monsoon). The bioconcentration factor (BCF) values of Cd, Pb, Mn, and Ni in root and stem were greater than 1 during both periods which indicates the metal accumulation potential of I. carnea. There is a dearth of study recommending the safe and effective green technology for the phytoremediation of FA dumps. In this regards, I. carnea was identified as an effective plant for phytoremediation in harsh environmental conditions of abandoned FA deposits. © 2012 Elsevier B.V.
