Malaria is a life threatening disease caused by microscopic parasites called Plasmodium that are transmitted to human beings by mosquitoes. Single celled Eukaryotic plasmodium parasite is responsible to cause malaria in human beings and is transmitted by bite of Anopheles species mosquitoes. Resurgence of malaria towards the end of 20th Century is due to failure of its eradication completely. Parasite recurrence occurs due to high densities of parasite, low immunity and non opimized drug concentration. The ineffective eradications strategies were due to indefinable complex life cycle of Plasmodium and emergence of drugs resistant strains of Plasmodium falciparum (Pf) including Artemisinin and Artemisinin based combination therapy (ACT). The vector of the disease i.e. mosquitoes became resistive towards Pyrethroids, which are only class of insecticides recommended for vector control. Artemisinin based combination therapy gained acceptance as an effective approach to counter the spread of disease resistance to chloroquine, sulfadoxine, pyrimethamine and other anti malarial drugs. Understanding the underlying molecular basis of the pathogenesis led to the development of some new diagnostic, drugs and insecticides. Reports on the use of new combination therapies reduced the burden of disease worldwide. Some of the new combination therapies are in clinical stage of development that have efficacy against drug resistant parasites and the potential to use in single dose regimens to improve compliance. The current review represents the recent anti-malarial research carried out globally especially in the class of synthesis of small molecule and natural product derivatives as potent anti-malarial drugs. The review also covers the advancement in the anti-malarial vaccine development although goal for vaccine development still remains elusive.

The newly synthesized compounds (3a-d) were in vivo evaluated for their anticonvulsant activity against yohimbine hydrochloride- induced epilepsy in comparison with 2mg/kg diazepam as a reference drug. The anticonvulsant effect of the intended compounds was assessed by their ability to delay the onset of seizure attack and by a reduction in the number of attacks. All of the synthesized compounds were found to have anticonvulsant activity.

We recently reported a new C3-symmetric (R)-phenylglycinol N-1,3,5-benzenetricarboxylic acid-derived chiral high-performance liquid chromatography (HPLC) stationary phase (CSP 1) that demonstrated better results as compared to a previously described N-3,5-dintrobenzoyl (DNB) (R)-phenylglycinol-derived CSP. Over a decade ago, (S)-leucinol, (R)-phenylglycine, and (S)-leucine derivatives were used as the starting materials of 3,5-DNB-based Pirkle-type CSPs for chiral separation. In this study, three new C3-symmetric CSPs (CSP 2, 3, and 4) were prepared by combining the ideas and results mentioned above. Here we describe the synthetic procedures and applications of the new C3-symmetric CSPs (CSP 2?CSP 4).

Since the discovery of (l)-phosphinothricin in the year 1970, the development of alpha-amino acids bearing a phosphorus group has been of renewed interest due to their diverse applications, including their use in [18F]-fluorolabeling, as fluorescent probes, as protecting groups and in the reversible immobilization of amino acids or peptide derivatives on carbon nanomaterials. Considerable progress has also been achieved in the field of antiviral agents, through the development of phosphoramidate prodrugs, which increase significantly the intracellular delivery of nucleoside monophosphate and monophosphonate analogues. This review aims to summarize the strategies reported in the literature for the synthesis of P(iii), P(iv) and P(v) phosphorus-containing amino acids with P-C, P-O, P-S or P-N bonds in the side chains and their related applications, including their use in natural products, ligands for asymmetric catalysis, peptidomimetics, therapeutic agents, chemical reagents, markers and nanomaterials. The discussion is organized according to the position of the phosphorus atom linkage to the amino acid side chain, either in an alpha-, beta-, gamma- or delta-position or to a hydroxyl, thiol or amino group.
