FCE 22250 (3-(N-piperidinomethylazino)methylrifamycin SV) is a member of the new class of 3-azinomethylrifamycins characterized by a long persistance in animals, a good oral absorption and a broad antibacterial spectrum including mycobacteria. In the experimental mice infection sustained by Mycobacterium tuberculosis H37Rv, FCE 22250 shows an efficacy 14 times higher than rifampicin and is still therapeutic when administered once every three weeks.

TLDR
New rifamycins have been developed that are as active as rifampin against mycobacteria but that also offer the advantage of high and prolonged serum levels and thus have the potential for once-weekly administration.
Rifamycins e Obstacles and opportunities
TLDR
This review of the state-ofthe-art regarding rifamycins suggests that it is quite possible to devise improved rIFamycin analogs, and improved activity against rifampin-resistant strains by some analogs promises that further work in this area, especially if the information from co-crystal structures with RNA polymerase is applied, should lead to even better analogs.
Activity in vitro of Rifabutin, FeE 22807, Rifapentine, and Rifampin against Mycobacterium microti and M. tuberculosis and Their Penetration into
TLDR
None of the rlfamyclns were concentrated In macrophages, the MICs being higher In the macrophagesthan In vitro by a factor of 2·fold for rlfabutin, 6.7·foldFor rlfampin, 20· fold for FCE 22807, and 26·fold For rlfapentine.
IN VITRO OBSERVATIONS ON THE SlJlTABlLlTY OF NEW RIFAMYCHUS FOR THE INTERMIlTENT CHEMOTHERAPY OF TUBERCULOSIS
TLDR
Six new rifamycin derivatives-F22, having high bactericidal activity against stationary organisms and a long half-life, was considered likely to be the most effective sterilising drug.
New Drugs and Strategies for Chemotherapy of Tuberculosis
TLDR
By and large, availability of several powerful drugs and, more importantly, the evolution of optimal regimens and proper application of specific antituberculosis chemotherapy with these drugs should be given credit for this success.

TLDR
The spiropiperidylrifamycin LM 427 displays a broad spectrum of potent antibacterial activity in vitro and in vivo and is particularly effective in the therapy of experimental tubercular infections of mice.

TLDR
The in vitro activity of LM 427 was tested in vitro against strains of the Mycobacterium avium complex and strains of M. tuberculosis, and showed that all strains susceptible to rifampin were also susceptible to LM 427.
A simplified method of evaluating dose-effect experiments.
TLDR
The method provides means for the rapid test of parallelism of two curves and easy computation of relative potency with its confidence limits and its accuracy is commensurate with the nature of dose-per cent effect data.
