Studies directed toward anti-HIV compounds

Classification of Anti-HIV Compounds using QSAR Studies

The Acquired Immunodeficiency Syndrome (AIDS) is one the most fatal disorders for which there have been no complete or successful chemotherapy yet. The pandemic spread of this disease has prompted an unprecedented scientific clinical effort to understand and propagate ways to combat it. Quantitative Structure–Activity Relationship (QSAR) study has been reportedly used to study topological indic...

Anti-inflammatory and Anti-HIV Compounds from Swertia bimaculata.

Three new compounds (1 - 3), including a sesterterpenoid, aspterpenacid C (1), with an unusual 5/3/7/6/5 pentacyclic skeleton, together with seven known ones (4 - 10), were isolated from the ethanol extract of the traditional Chinese medicinal plant Swertia bimaculata. Their structures were elucidated on the basis of the methods of spectroscopic NMR, MS, and computational chemistry. The structu...

Studies directed toward labeling analysis of angiotensin II in plasma.

We assay a 1-mL plasma sample containing angiotensin II (103 pg by radioimmunoassay) for the hormone by the following sequence of steps: add 125I-labeled val5-angiotensin II as an internal standard, extract on a C18 Sep Pak column, extract on an antibody affinity column, label the extract with an 125I Bolton-Hunter reagent, separate on a Bio Gel P2 column, and repetitively separate on a reverse...

Studies Directed toward the Synthesis of Nakadomarin A.

The application of a Pummerer-initiated tandem reaction cascade leads to the highly stereoselective formation of the tetracyclic core of Nakadomarin A.
