5-fluorouracil (5-FU) is a chemotherapeutic agent that has been used for the treatment of a variety of malignancies since its initial introduction to the clinic in 1957.(1) Due to its short biological half-life, multiple dosings are generally required to maintain effective 5-FU plasma concentrations throughout the therapeutic period. Clinical studies have shown that continuous 5-FU administration is generally superior to bolus injection as exhibited by lower toxicities and increased therapeutic efficacy.(2,3) Optimal therapeutic efficacy, however, is often compromised by the limiting therapeutic index...

Epoxyazadiradione (EAD) is an important limonoid present in Neem (Azadirachta indica) plant. In the present study, we have purified EAD from Neem seed and studied its anticancer potential in human cervical cancer (HeLa) cells. Cell proliferation inhibition studies indicated that the GI50 value of EAD is 7.5 ± 0.0092 μM in HeLa cells, whereas up to 50 μM concentrations EAD did not affect the growth of normal H9C2 cells. The control drug cisplatin inhibited the growth of both HeLa and H9C2 cells with a GI50 value of 2...

Pain encompasses both sensory and affective dimensions which can be differentially modulated by drugs. Here, we compare the pharmacological sensitivity of the sensory and affective responses using acetic acid-induced abdominal writhings (sensory-reflexive outcome) and acetic acid-induced depression of reward seeking behaviour (RSB, affective-nonreflexive outcome) to a highly palatable food in mice. We found that the expression of RSB critically depends on factors such as sex and previous knowledge and type of the food stimulus...

In living systems, environmental stress due to biotic and abiotic factors triggers the production of myriad metabolites as a potential mechanism for combating stress. Among these metabolites are the small polycationic aliphatic amine molecules - polyamines, which are ubiquitous in all living organisms. In this work, we demonstrate a correlation between cellular concentration of three major polyamines (putrescine, spermidine and spermine) with lead exposure on bacteria for a period of 6-24 h. We report that indigenously isolated Halomonas sp...

Hybrid inorganic-organic superlattice with an electron-transmitting but phonon-blocking structure has emerged as a promising flexible thin film thermoelectric material. However, the substantial challenge in optimizing carrier concentration without disrupting the superlattice structure prevents further improvement of the thermoelectric performance. Here we demonstrate a strategy for carrier optimization in a hybrid inorganic-organic superlattice of TiS2[tetrabutylammonium] x [hexylammonium] y , where the organic layers are composed of a random mixture of tetrabutylammonium and hexylammonium molecules...

The high number of poorly water soluble compounds in drug development has increased the need for enabling formulations to improve oral bioavailability. One frequently applied approach is to induce supersaturation at the absorptive site, e.g. the small intestine, increasing the amount of dissolved compound available for absorption. However, due to the stochastic nature of nucleation, supersaturating drug delivery systems may lead to inter- and intrapersonal variability. The ability to define a feasible range with respect to the supersaturation level is a crucial factor for a successful formulation...

2,3-Dihydro-3β-methoxy withaferin-A (3βmWi-A) is a natural withanolide that is structurally close to withaferin-A (Wi-A), is cytotoxic to human cancer cells, and is a candidate anticancer natural compound. Using cell-based biochemical, molecular, and imaging assays, we report that Wi-A and 3βmWi-A possess contrasting activities. Whereas Wi-A caused oxidative stress to normal cells, 3βmWi-A was well tolerated at even 10-fold higher concentrations. Furthermore, it promoted survival and protected normal cells against oxidative, UV radiation, and chemical stresses...
