Abstract
A series of quinoline derivatives (4a-4o) have been synthesized and their biological activities were also evaluated as potential telomerase inhibitors. Bioassay tests demonstrated that most of the compounds exhibited substantial broad-spectrum antitumor activity against the three cancer cell lines (HepG2, SGC-7901 and MCF-7). Moreover, all the title compounds were assayed for telomerase inhibition using the TRAP-PCR-ELISA assay. Compounds 4d and 4i displayed the most potent anticancer activities, which were comparable to the positive control. Docking simulation was performed to position compounds 4d and 4i into the telomerase structure active site to determine the probable binding model. Compounds 4d and 4i with potent inhibitory activity in tumor growth inhibition may be potential anticancer agents.

Abstract
In this review, we summarize the current "state of the art" of carbapenem antibiotics and their role in our antimicrobial armamentarium. Among the β-lactams currently available, carbapenems are unique because they are relatively resistant to hydrolysis by most β-lactamases, in some cases act as "slow substrates" or inhibitors of β-lactamases, and still target penicillin binding proteins. This "value-added feature" of inhibiting β-lactamases serves as a major rationale for expansion of this class of β-lactams. We describe the initial discovery and development of the carbapenem family of β-lactams. Of the early carbapenems evaluated, thienamycin demonstrated the greatest antimicrobial activity and became the parent compound for all subsequent carbapenems. To date, more than 80 compounds with mostly improved antimicrobial properties, compared to those of thienamycin, are described in the literature. We also highlight important features of the carbapenems that are presently in clinical use: imipenem-cilastatin, meropenem, ertapenem, doripenem, panipenem-betamipron, and biapenem. In closing, we emphasize some major challenges and urge the medicinal chemist to continue development of these versatile and potent compounds, as they have served us well for more than 3 decades.

Abstract
In present study, a series of new 1,3,4-oxadiazole derivatives containing 1,4-benzodioxan moiety (6a-6s) as potential telomerase inhibitors were synthesized. The bioassay tests demonstrated that compounds 6k, 6l, 6m, 6n and 6s exhibited broad-spectrum antitumor activity with IC(50) concentration range from 7.21 μM to 25.87 μM against the four cancer cell lines, HEPG2, HELA, SW1116 and BGC823. Moreover, all the title compounds were assayed for telomerase inhibition using the TRAP-PCR-ELISA assay. The results showed compound 6k possessed the most potent telomerase activity (IC(50)=1.27 ± 0.05 μM). Docking simulation was performed to position compound 6k into the active site of telomerase (3DU6) to determine the probable binding model.

Abstract
Classical Volsurf approach was applied to a set of 70 carbapenem compounds acting as antibiotics. Antibacterial activity of Staphylococcus aureus SG 511 and Escherichia coli 078 representing Gram positive and Gram negative bacteria, respectively, was used for the analysis. The score plots obtained from principal component analysis showed clustering of compounds according to the activity and their loading plots explained the Volsurf descriptors responsible for the separation or peculiar behaviour of these compounds. Partial Least Square analysis yielded a seven component model for S. aureus with a cross-validated r2 (q2) value of 0.684 and conventional r2 value of 0.883 and for E. coli it is a six component model with cross-validated r2 (q2) value of 0.514 and conventional r2 value of 0.756. Both the PCA and PLS models were validated by an external test set of 15 compounds. All the compounds of the test set were fairly predicted with residual values less than one log unit. Comparatively activity data of S. aureus (Gram positive) was better explained than E. coli (Gram negative) by these models.

Abstract
The synthesis and antibacterial activity of novel 1beta-methylcarbapenems 1a-f bearing oxyiminopyrrolidinylamide moiety at C-5 position of pyrrolidine are described. Most compounds exhibited comparable antibacterial activity to meropenem against a wide range of Gram-positive and Gram-negative organisms including Pseudomonas aeruginosa isolates. Of these carbapenems, 1a showed potent and broad spectrum of antibacterial activity and similar stability to DHP-I to meropenem. Against clinical isolates of 40 Gram-negative bacterial species including MDR and ESBL-producing strains, the selected carbapenem 1a possessed excellent in vitro activity except for MDR P. aeruginosa, and was comparable in potency to meropenem.

Abstract
Amides derived from fluorinated pyrrolidines and 4-substituted cyclohexylglycine analogues have been prepared and evaluated as inhibitors of dipeptidyl dipeptidase IV (DP-IV). Analogues which incorporated (S)-3-fluoropyrrolidine showed good selectivity for DP-IV over quiescent cell proline dipeptidase (QPP). Compound 48 had good pharmacokinetic properties and was orally active in an oral glucose tolerance test in lean mice.

Abstract
In 1999 the number of new compounds reported in the anti-infective field decreased significantly in comparison with previous years, especially for antifungals. The reported new compounds are mainly directed against Staphylococcus aureus isolates resistant to methicillin. Few derivatives were reported in the field of anti-infectives for gram-negative bacteria. At the moment, we are in a period of discovery as we await novel compounds that could issue from new engineering.
