Abstract
C(sp3)-H alkylation at α-position of methyl-keto group on D-ring of Steroidal diglycoside (SG) with (i) C=N of Schiff base imines to form amine derivatives and (ii) C=C of acrylate Michael acceptors to form Markovnikov ester products using AuCl3/NHC as pre-catalyst and Ag(I) salts as co-catalyst was described. The original form of SG (1) and its derivatives (3b-f & 5a-d) were screened for in vitro anti-cancer activity specifically on two breast cancer cell lines (i.e. MCF-7, MDA-MB-231) and deduced the structure-activity-relationship with the support of molecular docking studies. Among these compounds 3b, 3f, 5b & 5d have shown more potent anticancer activity than standard drug cisplatin with considerable IC50 values.

Abstract
Biocatalytic reduction of prochiral ketones using freshly ripened clementine mandarin (Citrus reticulata) in aqueous medium is reported. High enantioselectivities were observed, especially for the bioreduction of indanone , tetralone , and thiochromanone with respectively 95%, 99%, and 86% enantiomeric excess (ee). Enantioselective bio- and metal-catalyzed reactions were compared. Chiral ruthenium catalysts afforded good asymmetric inductions (>75% ee) in most cases, enantiomeric excesses depending on the nature of substrate and ligand. N-aminoindanol prolinamide was revealed as the best ligand for most ketones. Interestingly, for several substrates both enantiomers could be obtained using either Citrus reticulata or ruthenium complex.

Abstract
Inclusion of metabolic considerations in the drug design process leads to significant development in the field of chemical drug targeting and the design of safer drugs during past few years which is a part of an approach now designated as Retro metabolic drug design (RMDD). This approach represents systematic methodologies that integrate structure-activity and structure-metabolism relationships and are aimed to design safe, locally active compounds with an improved therapeutic index. It embraces two distinct methods, chemical delivery systems and a soft drug approach. Present review recapitulates an impression of RMDD giving reflections on the chemical delivery system and the soft drug approach and provides a variety of examples to embody its concepts. Successful application of such design principles has already been applied to a number of marketed drugs like esmolol; loteprednol etc., and many other candidates like beta blockers, ACE inhibitors, alkylating agents, antimicrobials etc., are also under investigation.

Abstract
The underlying inflammation present in chronic airway diseases is orchestrated by increased secretion of CC and CXC chemokines that selectively recruit the leukocyte populations into the pulmonary system. Human chemokines, eotaxins (CCL11 and CCL26), RANTES, and interleukin (IL)-8, are dramatically upregulated through G-protein receptors in cell inflammation, including human asthma. In previous studies, a series of new glucocorticoid antedrugs (GCAs) were synthesized as derivatives of isoxazoline and oxime, and their pharmacological properties based on the antedrug concepts were evaluated. Utilizing both human airway epithelium (HAE) and eosinophil (EOS) cell culture models, we carried out studies to test the hypothesis that new GCA cell treatment would ameliorate Th-1/Th-2-driven secretion of these asthmatic biomarkers, eotaxins (CCL11 and CCL26), RANTES, and IL-8 chemokines, that would in turn decrease recruitment, proliferation, and activation of EOS cells. Results demonstrate that isoxazoline and oxime derivatives exhibit concentration-dependent inhibition, and specifically the compound No. 7 decreases significantly the secretion of eotaxins, RANTES, and IL-8 in cytokine-stimulated HAE cells. It was shown that EOS proliferation and activation were reduced considerably, and cell apoptosis occurred when exposed to nonfluorinated isoxazoline derivatives. These results provide evidence that concentration and structural manipulation of GCAs could increase the anti-inflammatory potency in treatment of chronic diseases, including asthma.

Abstract
Prochiral heteroaryl ketones containing furan, thiophene, chroman and thiochroman moieties were successfully reduced in the presence of 1 - 10 mol % of spiroaminoborate ester 1 with different borane sources to afford non-racemic alcohols in up to 99% ee. In addition, modest enantioselectivity, around 80% ee, was achieved in the reduction of linear α,β-unsaturated heteroaryl ketones.

Abstract
A series of new anti-inflammatory steroidal antedrugs with C-16,17-isoxazoline ring system were synthesized and their pharmacological activities were evaluated. We reported earlier that these compounds are promising antedrugs based on the results of 5-day rat croton oil ear edema assay. In the present study, most of these compounds showed high binding affinities to the glucocorticoid receptor of liver cytosol. 21-acetyloxy-9alpha-fluoro-11beta-hydroxy-3,20-dioxo-1,4-pregnadieno [16alpha,17alpha-d] isoxazoline (FP-ISO-21AC) and 11beta,21-dihydroxy-9alpha-fluoro-3,20-dioxo-1,4-pregnadieno [16alpha,17alpha-d] isoxazoline (FP-ISO-21OH) were found 5.0-, 5.3-fold more potent than prednisolone, respectively. Inhibitory effects of the antedrugs on the nitric oxide (NO) production were assessed using LPS-stimulated RAW 264.7 murine macrophage cells. All these steroidal antedrugs exhibited concentration-dependent inhibition of NO production, but their relative potencies were lower than prednisolone. In vitro metabolism study in rat plasma showed that FP-ISO-21AC and 21-acetyloxy-9alpha-fluoro-11beta-hydroxy-3,20-dioxo-1,4-pregnadieno [16alpha,17alpha-d]-3'-hydroxyiminoformyl isoxazoline (FP-OXIM-21AC) were hydrolyzed rapidly, with the half-lives of 2.1 and 4.2 min, respectively. The half-lives of FP-ISO-21OH and 11beta,21-dihydroxy-9alpha-fluoro-3,20-dioxo-1,4-pregnadieno [16alpha,17alpha-d]-3'-hydroxyiminoformyl isoxazoline (FP-OXIM-21OH) were 92.2 and 110.2 min, respectively.

Abstract
A series of 2-substituted aminomethyloxy naphthalenes 1 and 4-(1-naphthoxy-2-substituted aminomethyl)-butanoic acids 2 were synthesized by Mannich reaction of 4-(2-naphthoxy)-butanoic acid 3 and 4-(1-naphthoxy)-butanoic acid 4 with appropriate secondary amines and para-formaldehyde. The newly synthesized compounds were tested for their hypotensive activity at 5 mg/kg i.v. dose in cats. The results indicated that the analogue 2-(N4-phenyl-N1-piperazino)-methyloxy naphthalene 1d (> N = N4-phenyl-N1-piperazino) was the most active analogue when its hypotensive activity was compared to the reference compound propranolol.

Abstract
The prodrug and antedrug concepts, which were developed to overcome the physical and pharmacological shortcomings of various therapeutic classes of agents, employ diametrically different metabolic transformations. The prodrug undergoes a predictable metabolic activation prior to exhibiting its pharmacological effects in a target tissue while the antedrug undergoes metabolic deactivation in the systemic circulation upon leaving a target tissue. An increased therapeutic index is the aspiration for both approaches in designing as well as evaluation criteria. The recent research endeavors of prodrugs include the gene-directed and antibody-directed enzymatic activation of a molecule in a targeted tissue, organ specific delivery, improved bioavailabilities of nucleosides and cellular penetration of nucleotides. As for antedrugs, emphasis in research has been based upon the design and synthesis of systemically inactive molecule by incorporating a metabolically labile functional group into an active molecule.
