“Building blocks of existence”?! What a great way to start a polemic. A big thank you to materialists everywhere for perpetuating this misnomer.

The messenger RNA now binds to a ribosome, where the messageis translated into a sequence of amino acids. The amino acidsthat are incorporated into the protein being synthesized arecarried by relatively small RNA molecules known as transferRNA, or tRNA. There are atleast 60 tRNAs, which differ slightly in their structures, ineach cell. At one end of each tRNA is a specific sequence ofthree nucleotides that can bind to the messenger RNA. At theother end is a specific amino acid. Thus, each three-nucleotidesegment of the messenger RNA molecule codes for the incorporationof a particular amino acid. The relationship between thetriplets, or codons, on the mRNA and the amino acids is shown inthe table below.

We supply building blocks for combinatorial chemistry and intermediates for organic synthetic chemistry. Our major products include the kinds of compounds that cannot be found in the major catalogues, such as boronic acids, heteroaromatic acids, amines (primary and secondary) and aldehydes.

The breast cancer resistance protein (BCRP, ABCG2) is among the latest discovered ABC proteins to be involved in MDR phenotype and for which only few inhibitors are known. In continuing our program aimed at discovering efficient multidrug resistance modulators, we conceived and synthesized new acridones as ABCG2 inhibitors. The design of target molecules was based on earlier results dealing with ABCG2 inhibition with flavone and chromone derivatives. The human wild-type (R482) ABCG2-transfected cells were used for rational screening of inhibitory acridones. The synthesis of target compounds, the inhibitory activity against ABCG2, and structure-activity relationships are described. One of the acridones was even more potent than the reference inhibitor, GF120918, as shown by its ability to inhibit mitoxantrone efflux.

Synthesis of molecules with specific chirality can be difficult; however, it is an important target of many chemists as they seek to obtain desired materials.

The findings, reported in the Royal Society of Chemistry's ChemComm, show that the synthesized chiral molecules contain imidazoline rings--five-membered rings containing two nitrogen and three carbon atoms.

Design and Synthesis of Biologically Active Molecules - IIBR

Mechanically interlocked molecular compounds can be synthesized in high yields by using template-directed assistance to covalent synthesis. Catenanes and rotaxanes are two classes of mechanically interlocked molecules that have been prepared using a variety of methods such as "clipping", "slipping", and "threading-followed-by-stoppering", under both kinetic and thermodynamic regimes. These different methods have utilized a range of templates such as transistion metals, π-donor/π-acceptors, and hydrogen-bonding motifs. Multivalency has emerged as another tool to aid and abet the supramolecularly assisted synthesis of mechanically interlocked molecules. Recent advances in our understanding of the nature of the mechanical bond has led to the construction of molecular machines with controllable motions that have, in one instance, been introduced into molecular electronic devices.
