Abstract
The 1,5-benzothiazepane structure is an important heterocyclic moiety present in a variety of commercial drugs and pharmaceuticals. This privileged scaffold exhibits a diversity of biological activities, including antimicrobial, antibacterial, anti-epileptic, anti-HIV, antidepressant, antithrombotic and anticancer properties. Its important pharmacological potential renders research into the development of new and efficient synthetic methods of high relevance. In the first part of this review, an overview of different synthetic approaches toward 1,5-benzothiazepane and its derivatives is provided, ranging from established protocols to recent (enantioselective) methods that promote sustainability. In the second part, several structural characteristics influencing biological activity are briefly explored, providing a few insights into the structure-activity relationships of these compounds.

Abstract
The dormant state of bacterial spores is generally thought to be devoid of biological activity. We show that despite continued dormancy, spores can integrate environmental signals over time through a preexisting electrochemical potential. Specifically, we studied thousands of individual Bacillus subtilis spores that remain dormant when exposed to transient nutrient pulses. Guided by a mathematical model of bacterial electrophysiology, we modulated the decision to exit dormancy by genetically and chemically targeting potassium ion flux. We confirmed that short nutrient pulses result in step-like changes in the electrochemical potential of persistent spores. During dormancy, spores thus gradually release their stored electrochemical potential to integrate extracellular information over time. These findings reveal a decision-making mechanism that operates in physiologically inactive cells.

Abstract
BACKGROUND Despite the availability of a variety of chemotherapeutic agents, cancer is still one of the leading causes of death worldwide because of the problems with existing chemotherapeutic agents like objectionable side effects, lack of selectivity, and resistance. Hence, there is an urgent need for the development of novel anticancer agents with high usefulness, fewer side effects, devoid of resistance and superior selectivity. OBJECTIVE The objective of this study is to synthesize a series of novel 1,5-benzothiazepine derivatives and evaluate their anticancer activity employing biological and computational methods. METHODS Twenty new benzothiazepines (BT1-BT20) were prepared by condensing different 1-(4- isobutylphenyl)ethanone chalcones with 2-amiothiophenol and evaluated for their anticancer activity by MTT assay against three cell lines including HT-29 (colon cancer), MCF-7 (breast cancer) and DU-145 (prostate cancer). These compounds were also tested for their inhibitory action against EGFR (Epidermal Growth Factor Receptor) tyrosine kinase enzyme by taking into account of their excellent action against colon and breast cancer cell lines. Further, the structural features responsible for the activity were identified by Pharmacophorebased modelling using Schrodinger's PHASETM software. RESULTS Among the 20 benzothiazepine derivatives, three compounds viz., BT18, BT19 and BT20 exhibited promising activity against the cell lines tested and the activity of BT20 was more than the standard methotrexate. Again the above three compounds showed excellent inhibitory activity with the percentage inhibition of 64.5, 57.3 and 55.8 respectively against EGFR (Epidermal Growth Factor Receptor) tyrosine kinase. PHASE identified a five-point AHHRR model for the proposed activity and the computational studies provided insights into the structural requirements for the anticancer activity and the results were consistent with the observed in vitro activity data. CONCLUSION These novel benzothiazepines will be useful as lead molecules for the further development of new cancer therapies against colon and breast cancers.

Abstract
A novel and practical asymmetric synthesis of chiral glycidic acid derivatives involving methyl (2R,3S)-3-(4-methoxyphenyl)glycidate ((2R,3S)-2a), a key intermediate for diltiazem hydrochloride (1), was developed. Treatment of methyl (E)-4-methoxycinnamate ((E)-3a) with chiral dioxirane, generated in situ from a catalytic amount (5 mol %) of an 11-membered C(2)-symmetric binaphthyl ketone (R)-7a, provided (2R,3S)-2a in 92% yield and 80% ee. Other cinnamic acid esters and amides were epoxidized by the use of the same procedure to give the corresponding chiral glycidic acid derivatives with up to 95% yield and 92% ee. Higher enantioselectivities in the asymmetric epoxidation of (E)-cinnamates than that of (E)-stilbene derivatives were observed and were proposed to be attributed to a dipole-dipole repulsion between oxygen atoms of an ester group in the cinnamates and those of the lactone moieties in the binaphthyl dioxirane.

Abstract
A parallel solution-phase synthesis of 2-quinoxalinol analogues is described. The key step-simultaneous reductions of m-Ar(NO2)2 to m-Ar(NH2)2 was investigated extensively. We obtained preliminary pharmacological activity of those analogues for the inhibition of LPS-induced TNF-alpha release on mouse macrophage in vitro. Two compounds revealed inhibitory activity, with IC50 values of 0.40 microM (7-amino-6-[(3-methoxypropyl)amino]-3-methyl-2-quinoxalinol) and 2.2 microM (7-amino-6-[(3-butoxypropyl)amino]-3-methyl-2-quinoxalinol), respectively.
