Eosinophilic Meningitis and Intraocular Infection Caused by Dirofilaria sp. Genotype Hongkong.

Eosinophilic meningitis caused by human diroflarial infection is rare. We report a case of eosinophilic meningitis and concomitant intraocular dirofilarial infection in India. Sequencing of the mitochondrial genome identified the worm as Dirofilaria sp.

Prevalence of scrub typhus in a tertiary care centre in Telangana, south India.

Background And Objectives: Scrub typhus is re-emerging as an important cause of acute undifferentiated fever in the last decade from various parts of India. Complexity in performing the "gold standard" immunofluorescent assay and the unreliable nature of Weil Felix test often results in delayed or misdiagnosis in a majority of cases. The present study seeks to integrate the results of rapid diagnostic tests, clinical and laboratory features to aid the diagnosis and management of scrub typhus patients.

Total synthesis and in vitro bioevaluation of clavaminols A, C, H & deacetyl clavaminol H as potential chemotherapeutic and antibiofilm agents.

A highly concise and expedient total synthesis of bioactive clavaminols (1-4) has been executed using commercially available achiral compound decanol. The synthetic strategy relied on trans-Wittig olefination, Sharpless asymmetric epoxidation, regioselective azidolysis and in situ detosylation followed by reduction as key reactions with good overall yield. Based on biological evaluation studies of all the synthesized compounds, it was observed that the clavaminol A (1) exhibited good cytotoxicity against DU145 and SKOV3 cell lines with IC50 value of 10.

Design, synthesis and in vitro biological evaluation of short-chain C12-sphinganine and its 1,2,3-triazole analogs as potential antimicrobial and anti-biofilm agents.

A conceptual synthetic approach of short-chain C12-sphinganine 1 and a small library of its 1,2,3-triazole analogs 2(a-f) has been accomplished using the commercially available and inexpensive 10-undecenoic acid as a starting material. Miyashita's C-2 selective endo mode azidolysis and Huisgen click reaction was employed for the synthesis of the designed analogs. Based on biological evaluation studies of all the synthesized compounds, it was observed that, (2S,3R)-2-(4-(3-hydroxyphenyl)-1H-1,2,3-triazol-1-yl)dodecan-1,3-diol (2b) exhibited promising antimicrobial and antifungal activities.
