Description
Noformicin is produced by the strain of Nocardia formica. It has inhibitory effect on mumps virus and Newcastle disease virus in chicken embryo. It also extended the survival of mice infected with swine, influenza A (PR8) and influenza B (Lee) viruses.

1. In vivo antiviral properties of biologically active compounds. II. Studies with influenza and vaccinia viruses
R W Sidwell, G J Dixon, S M Sellers, F M Schabel Jr Appl Microbiol. 1968 Feb;16(2):370-92. doi: 10.1128/am.16.2.370-392.1968.
The in vivo anti-influenza virus and antivaccinia virus activity of 156 biologically active compounds was determined. One of two criteria was used for evaluating activity against the influenza virus. The criteria were increase in survivor number and mean survival time, and reduction in virus-induced lung consolidation in treated, infected Swiss mice. Increase in survivor number and mean survival time were the criteria for evaluation of antivaccinia virus activity. Several drug doses were tested against two virus concentrations to demonstrate antiviral activity more clearly. Two compounds were considered significantly active against the influenza virus: DL-noformicin (NSC 72942) and amantadine hydrochloride (NSC 83653). Eleven compounds had reproducible activity against vaccinia virus: isatin-beta-thiosemicarbazone (NSC 721), 6-azauracil (NSC 3425), 9-alpha-fluoro-2alpha-methylhydrocortisone 21-acetate (NSC 12601), 5-[bis(2-chloroethyl)amino]uracil (NSC 34462), 5-iodo-2'-deoxyuridine (NSC 39661), streptonigrin (NSC 45383), N-methylisatin beta-thiosemicarbazone (NSC 69811), cytovirin (NSC 91770), 9-beta-D-arabinofuranosyladenine (NSC 404241), and 5-(mercaptomethyl)uracil (NSC 529351).
2. The natural product noformycin is an inhibitor of inducible-nitric oxide synthase
B G Green, R Chabin, S K Grant Biochem Biophys Res Commun. 1996 Aug 14;225(2):621-6. doi: 10.1006/bbrc.1996.1220.
Inducible-Nitric oxide synthase (iNOS, EC 1.14.13.39) catalyzes the formation of nitric oxide (NO) and L-citrulline from L-Arg. NADPH and dioxygen. The natural product, (-)-noformycin was found to be a potent, competitive inhibitor of recombinant human iNOS with respect to L-Arg with a Ki = 1.3 +/- 0.3 microM. The reversible binding of noformycin caused a high spin type I spectral perturbation of the iNOS heme group with a Kd = 1.5 +/- 0.2 microM. These results demonstrate that natural products may be a useful source for inhibitors of NO-biosynthesis.
3. Quantum chemical and molecular mechanics studies on the binding of stereoisomers of the oligopeptide antibiotics amidinomycin and noformycin to the minor groove of B-DNA
A M Sapse, W Feng, L Fugler-Domenico, S Kabir, T Joseph, J W Lown J Biomol Struct Dyn. 1993 Feb;10(4):709-26. doi: 10.1080/07391102.1993.10508002.
Ab initio calculations (Hartree-Fock) using the 6-31G basis set have been performed on two chiral oligopeptide antitumor antibiotics amidinomycin 5 and noformycin 6. The latter are DNA minor groove binding agents related to the A.T recognizing netropsin 4 and distamycin 3 but, unlike the latter, bear stereocenters (two for 5 and one for 6) that may be expected to affect binding to the B-DNA receptor. Geometry optimized conformations, energies and distribution of electrostatic charges within the molecules were derived. The rotational barrier for bond C3-C6 in 6 was calculated to be ca. 6 kcal.mole-1 and the dipole moment for 6 was 7.69D and for 5 was 5.58D. The ab initio derived parameters of the geometry optimized conformations of the different possible stereoisomeric forms of 5 and 6 were used to interpret their different interactions with the minor groove of DNA at both A.T and G.C sequences and the results were compared with molecular mechanics calculations. The order of binding of the four stereoisomers of 5 at the preferred (A.T)n sequences by both ab initio and molecular mechanics calculations is 1S,3R > RR > RS > SS. The predicted energy differences for complexation with DNA of the other stereoisomers from that of 1S,3R are: RR (4.2%); RS (6.7%) and SS (21.5%). In the case of noformycin the 4R structure binds more effectively than the enantiomer. Considerations of phasing in the computed distances between hydrogen bond donating sites in the DNA-bound antibiotics provide further insight into the binding processes. In the complexes of noformycin 6 the N-N1-N4 and N1-N5 distances (9.05 and 9.15 A respectively for 4R-6 and 9.23 and 9.26 A respectively for 4S-6) are close to the optimum value of 9.1 A for effective binding. In the case of amidinomycin 5 the best agreement with the optimum value occurs with the strongest binding diastereomer 1S,3R (N1-N3 = 8.91, N1-N4 = 9.41 A). The unexpected result, consistent in both ab initio and molecular mechanics treatments, is that, in contrast to the cases of kikumycin 1 and anthelvencin 2, the natural 3S configuration of 5 and 4S of 6 do not confer maximal binding efficiency. This suggests that biogenetic factors in the generation of the oligopeptide antibiotics lead to maximum DNA binding in the cases of kikumycin and anthelvencin but not in the cases of amidinomycin and noformycin.
