25 μg/mL in sterile tubes No.1–10. A 100 μL

sterile Muller Hinton Broth (MHB) was poured in each sterile tube followed by addition of 200 μL test compound in tube 1. Two fold serial dilutions were carried out from tube 1 to the tube 10 and excess broth (100 μL) was discarded from the last tube No. 10. To each tube, 100 μL of standard inoculums (1.5 × 108 cfu/mL) Cisplatin purchase was added. Turbidity was observed after incubating the inoculated tubes at 37 °C for 24 h.19 The primary screening was conducted at concentration of 250 μg/mL against M. tuberculosis H37Rv in the BACTEC 460 radiometric system. The MIC was defined as the lowest concentration inhibiting 99% of the inoculums ( Table 7). All authors have none to declare. We would like to thank Tamil Nadu State Council for Science and Technology (TNSCST), Chennai, Tamil Nadu. India, for the financial support to our research.

“Oral drug delivery is the most preferred route for drug administration as it is non-invasive in nature. However, poor solubility, stability, and bioavailability of many drugs make it difficult to achieve therapeutic levels. In oral route, the efficiency of drug delivery is directly related to particle size because particle size can improve the dissolution and thus can enhance bioavailability of the drug. Several strategies and Hedgehog antagonist formulations have been employed to overcome these limitations like use of salts of ionic drugs,1 complexing

with cyclodextrins,2 Modulators conjugation to dendrimers,3 use of co-solvents etc.4 Though these strategies have been shown to improve drug solubility, universal solubilization methods that can improve the drugs bioavailability significantly are still highly desirable.5 Nanotechnology as a delivery platform offers very promising applications in drug delivery, especially through and for the oral route. Either direct nanosizing or incorporation into polymeric and lipidic nanoparticles can help deliver drugs with poor aqueous solubility, low permeability, and extensive first pass metabolism.6 Using nanoparticles, it may be possible to achieve improved delivery of poorly water-soluble drugs by delivering drug in small particle size which increases the total surface area of the drugs thus allowing Adenosine faster dissolution and absorption in to the blood stream.7 Ceramic nanoparticles also called aquasomes, contribute to a new drug delivery systems comprised of surface modified nanocrystalline ceramic carbohydrate composites. These are nanoparticulate carrier systems with three layered self assembled structures. These consist of central solid nanocrystalline core coated with polyhydroxy oligomers onto which biochemically active molecules are adsorbed.8 For the preparation of nanoparticles core, both polymers (albumin, gelatin or acrylates) and ceramics (diamond particles, brushite, and tin oxide) can be used.
