873334-52-2 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 873334-52-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 8,7,3,3,3 and 4 respectively; the second part has 2 digits, 5 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 873334-52:
182 % 10 = 2
So 873334-52-2 is a valid CAS Registry Number.

Small multivalent architectures mimicking homotrimers of the TNF superfamily member CD40L: Delineating the relationship between structure and effector function

Synthetic multivalent ligands, owing to the presence of multiple copies of a recognition motif attached to a central scaffold, can mediate clustering of cell surface receptors and thereby function as effector molecules. This paper dissects the relationship between structure and effector function of synthetic multivalent ligands targeting CD40, a cell surface receptor of the tumor necrosis factor receptor (TNF-R) superfamily. Triggering CD40 signaling in vivo can be used to enhance immunity against intracellular pathogens or tumors. A series of multimeric molecules has been prepared by systematically varying the shape and the valency of the central scaffold, the nature and the length of the linker as well as the sequence of the receptor binding motif. The data reported here (i) suggest that radial distribution of CD40-binding units and C 3-symmetry are preferred for optimal binding to CD40 and signaling, (ii) underscore the importance of choosing an appropriate linker to connect the receptor binding motif to the central scaffold, and (iii) show the versatility of planar cyclic α- and β-peptides as templates for the design of CD40L mimetics. In particular, the (Ahx)3-B trimeric scaffold-linker combination equally accommodated binding elements derived from distinct CD40L hot-spot regions including AA″ loop and β-strand E. The use of miniCD40Ls such as those reported here is complementary to other approaches (recombinant ligands, agonistic anti-receptor antibodies) and may find interesting therapeutic applications. Furthermore, the results disclosed in this paper provide the basis for future design of other TNF family member mimetics.
